Media Library

Media Library

MediaLibrary is a multi-platform free software that lets you catalog your media files ( CD-Rs, DVDs...)

Its main purpose is to reference your media files in a category tree with any comment. You can then easily find any file you are looking for MediaLi


How to use computer resources in libraries —To make sure you can find what you are looking for, here are some tips to make the computers help you more effectively:

1. Have titles in mind —If you are heading to the library, it never hurts to have the titles you want in your mind already. This will allow you to easily type in the title names and then begin to use the books for your personal research. Double-check the title names before you leave for the library. 2. Know author names— If you do not know the titles, perhaps you know the names of authors and experts in the field. These will be easy to input into the computer to see what you can find.
3. Pick out keywords—When you are researching a specific subject, try to choose one to five keywords that come up frequently in the literature. For example, if you research "weight loss," you might also type in "diet." Have this list of keywords available to find as many related books as possible.
4. Have a question—Before you walk into the library, have a question or two that you are trying to answer. This will focus your research and allow you to make the most of your time.
5. Bring related book titles— If you already have done some research elsewhere, bring those titles along with you. Even if you already have those books at home, look for them in the library and then look to the right and the left of the book on the shelf. More often than not, those adjacent books will offer you additional ideas and information about your topic.Use a notepad. As you walk along, make sure to bring your notepad. This will keep track of the numbers and letters you need to find for each book or topic you research. The more numbers you have, the more you will head in the proper direction when you are in the library.
Using the library is easy and it only takes a little direction from you in order to fully realize how many books can help you with your topic of study.

Social Media in Libraries: It’s like, Complicated.
Nick Canty, University College London
This article considers how some major libraries across the world are using social media
platforms. Libraries have engaged with the ‘household brands’ familiar to us all regardless of
geographic location or language although their use of the platforms varies widely.
Although there are no surprises in how the platforms are used and what content is made
available by each library, the overall impression is of patchy use of the platforms, with some
libraries fully embracing all platforms while others concentrating on fewer. A key message is
that high quality images for websites seems to succeed in engaging with people.
The article is based around social media data collected from library accounts on Facebook,
Twitter, YouTube and Blogs between July and August 2012, extended for three months for
YouTube due to the lack of regularly submitted content. After a discussion about the role of
social media in libraries the data is analysed for each platform.
Keywords: Social media, libraries, online engagement, Library 2.0, Facebook, YouTube,
Twitter, Blogs
The growth of social media and social networking sites has been one of the most impressive
aspects of the internet in recent years and its popularity is undeniable. Twenty two percent of
all time spent online is spent on social media sites, or one in every four and a half minutes
and three quarters of global consumers who go online visit social media sites 1
Whether or
not we agree with the view that social media have the ability to break down the traditional
barriers between the public and the private by putting power in the hands of the user or take a
more sceptical view that social media is little more than a ‘daily me’ 2
or ‘mass self
communication’ 3
, it is safe to assume that social media is here to stay and is now a priority
for many organizations. The challenge for all organizations, but particularly acute for people
working in the information industry, is how to harness and exploit these communication
channels to best effect. The disputed and subjective term Library 2.0 is open to interpretation
but what is clear is that in a networked society library service is likely to be increasingly
virtual, participatory and collaborative with the focus on user centered change and
participation. In this scenario, also termed radical trust, the library becomes user generated 4

Engaging with social media is a step towards this scenario.
This article examines how social media tools are being used by some major libraries across
the world. The article is based on data analysis of library use of social media sites and
provides some insight into how libraries are engaging with social media. Libraries are

accustomed to technological change and many seem to have embraced social media with
enthusiasm. Much of the discussion around social media use in libraries has appeared in
practitioner publications rather than academic journals, a notable issue which suggests the
debate is still in the stage of direct knowledge transfer rather than analysis.
Social Media and Social Networks: Definitions and Descriptions
The networked society is today a reality with billions of people connected to the internet and
able to communicate through social media such as Twitter and Facebook. However, although
the terms social media, social networks and Web 2.0 have become ubiquitous it is worth
dissecting these terms to provide some clarity in this complex world. Drawing a line between
the related concepts of Web 2.0 and User Generated Content we could define social media as
‘a group of Internet-integrated applications that build on the ideological and technological
foundations of Web 2.0 (the platform) and that allow the creation and exchange of User
Generated Content (the ways in which people make use of social media)’5

There are no agreed definitions of the umbrella term ‘social media’ but the table below
provides a useful framework.

Kaplan, Haenlein (2010). Users of the world, unite! The challenges and opportunities of Social Media. P 61.
Business Horizons (2010) 53, 59—68.
Collaborative projects
These allow the joint creation and sharing of
content between users with the underlying
philosophy that the effort of many leads to better
outputs. The leading example here is Wikipedia.
Blogs can trace their history back to the earliest
days of the Internet but they took off around
1997-98. Today there are estimated to be more
more than 160 million blogs in existence, either
active or abandoned in cyberspace.
Content communities
The sharing of content across different media
types such as videos on YouTube, photos on Flickr
and PowerPoint on Slideshare.
Social networking sites
These are applications in which a social network’s
members serve dual roles as both the suppliers
and the consumers of content. Social networks
allow users to connect with each other and
exchange a wide variety of media content, be it
film, photos, text or audio files among others.
Increasingly used by corporations as a marketplace
to sell goods.
Virtual social worlds
In virtual worlds users choose their behaviour and
live as an avatar in a three dimensional
environment. The most prominent virtual world is
Second Life.
Virtual game worlds
These game worlds allow users to appear as
personal avatars and interact with others in in two
virtual worlds; games and social worlds. Games
require users to follow a set of rules in the context
of massively multiplayer online roleplaying games
(MMORPG). Examples here are Microsoft’s X Box
and Sony’s PlayStation. Users adopt a persona and
interact with other players across the world.
Six types of social media. Kaplan, Haenlein 2010
Why use social media in the library?
Social media can be powerful information dissemination tools and offer a way for libraries to
promote their activities, resources and services while allowing a two way dialogue with
stakeholders . A 2010 survey by the Society of Chief Librarians in the UK 6
found that
internet users trust library staff more than most other providers of online support and
information, and public library staff are second only to doctors in terms of the trust placed in
them by seekers of information. The core of the work of librarians is the sharing information
so this would suggest librarians are in a unique position to implement and exploit social
media to their (and their users) advantage.
Social media can be used in a variety of communication methods broadly summarized as
broadcast messages, response to enquiries and then conversation between institution and

users but regardless of the approach taken there are compelling reasons for libraries to engage
with social media. Social media can give a competitive edge in a time of major technological
change and with access to information widely available libraries need to demonstrate the
value of their proposition. Social media give librarians a way to reach out to their users who
may not have considered the library as a resource for their information needs.
1. Cost and ease of use
Setting up accounts and getting started is easy and free. Patrons use the same tools in their
social and work life so social media fit in with the workflow and expectations of many users.
However, judging what success looks like in social media is notoriously difficult as unlike in
conventional direct marketing where there are recognised response rates (a 1% return rate in
direct marketing is a commonly agreed industry norm), it is much harder to measure
something intangible like social media. Although there are the easy measures such as the
number of Twitter followers, Facebook likes and comments, measuring ‘engagement’ or
customer satisfaction is much more problematic. In addition a myth has arisen that suggests
that social media is completely ‘free’ when very real costs, particularly staff time, are
Good social media engagement requires considerable staff time and management
commitment to ensure the reputation of the library is enhanced in the eyes of users.
2. Communication with patrons
Social media offers an accessible way to engage with patrons and potential patrons,
particularly the elusive younger generation or ‘digital natives’ who are now entering the
workplace having grown up in a culture of sharing information, inviting others to contribute
and contributing to online discussions. It is a myth that young people are driving social
technologies and but they nevertheless are heavily active online and tend to see a clear
division between work/study and leisure activities and libraries have a specific function in the
work/study sphere.
The two-way communication that now exists between library and user can be helpful for
responding to user collection requests.
3. Marketing and promotion
For many organisations social media tools are used primarily as part of their marketing and
promotion activities. For libraries this enables them to communicate additions to collections,
promote exhibitions, talks and so on. It is worth remembering however that although social
media may provide the tools, the library still has to provide the content to promote and that
takes time and money. Social media can only promote what is feed into it.
4. A way to improve customer service
With so much focus on social media for marketing and broadcasting we overlook the
participatory nature of social media. Social media are frequently seen as tools for marketing
and promotion but they also offer the chance to improve customer service issues and
complaints. Social media allow an organization to monitor what’s being said about them and
respond to positive (and particularly negative) feedback quickly. There are now numerous
platforms which offer these services although libraries need to consider who is responsible
for this activity and how much time to devote to this as this hidden cost and rise.
This participatory communication method allows users to connect with knowledge curators
and trust to be built between the two parties.
To gain an insight into the social media use by libraries data was collected from the social
media sites used by six major libraries across the world; the British Library, the Library of
Congress, Biblioteca Nacional de Espana, Bibliotheque National de France, the National
Library of Australia, and the National Library of Scotland. All the libraries use the familiar
‘household brands’ we are familiar with despite their native languages and geographical
All the libraries have adopted a multichannel approach although each platform has particular
strengths and is appropriate for different uses. A framework to consider the appropriateness
of different channels was compiled by the British Informatics Society. Twitter is particularly
good for rapidly changing information and for connecting with communities whereas
YouTube is appropriate for demonstrating products. Corporate blogs may be considered for
general information sharing. 7 Getting the tome right for any channel is a major consideration.

Data in the tables in this article was captured between 22 July 2012 and 22 August 2012,
although for YouTube this was extended for three months as there was significantly less
activity on this platform. Social media statistics are a crude way to measure issues like
‘engagement’ or message pe*******on but they nevertheless provide a perspective on library
use of social media and in addition social media analytics are widely understood measures.
Visibility of Social Media on Library Homepages
Having social media buttons on the home page suggests an organization is active and seeking
to engage with external stakeholders. Finding social media sites therefore was easy
depending on whether the library had links on their home pages but embedding these links in
every page as headers or footers increases exposure. None of the libraries had a social media
dashboard that aggregated all social media activity on one page which is a useful way to
display content from disparate networks for visitors, as we all confirming which are the
official sites in case there may be fake accounts operating.
Some libraries however had dedicated pages describing their use of social media and if these
were available they are recorded in the table below.

The Library of Congress has comprehensive guidance and advice about its use of social
media and similarly the National Library of Scotland explains its social media presence with
a helpful ‘What others are saying’ link to a list of recent mentions on Twitter and other
platforms. The BNF provides similar links to its social media platforms in three languages.
With close to 1bn users across the world, Facebook is one of the most visited websites in the

All libraries populate Facebook with rich content which mix news, promotion of library
resources and information about current projects or exhibitions. The column ‘Main location’
refers to where most visitors to the pages are based. Not surprisingly the majority
of visitors to the libraries’ pages are local, coming from the capital city with the
exception of the National Library of Scotland which although located in Edinburgh saw most
visitors coming from Glasgow.
The exhibitions promoted are both live events such as the Writing Britain exhibition in the
British Library or Gyenes: Master Photographer at the Biblioteca Nacional de Espana in
Madrid, or virtual in the form of photo albums. All the libraries make use of the ‘events’
section although there are significant differences in how up to date content is here, with the
British Library scoring high for including future events as well as past events while other

libraries have not updated details here going back to 2010 thereby giving the impression of
forgotten or neglected pages.
The Biblioteca Nacional de Espana posts tended to be albums with richer content than the
other libraries and this may account for the very impressive ‘likes’ and ‘shares’ they enjoy
from what is only an average number of posts from this library.
Facebook was used for competitions by several libraries. The National Library of Scotland
was running a successful engagement campaign at the time of writing, inviting the public to
‘Scotishify’ famous film quotes as part of a exhibition on Scotland’s relationship with
cinema, with the best entries winning £100 in cinema tokens. There were over 2000 quotes
submitted to the gallery indicating considerable success engaging with the public with this
The experience of the NLS and BNE perhaps demonstrate the importance of providing high
quality and engaging content on Facebook. Both institutions post good images which people
respond well too.
Scotland at the Cinema. National Library of Scotland page 2012
The other competition was the British Library’s Race for Knowledge children’s online game
which gave children the chance to win an iPad as well as £2 off entry to the Writing Britain
exhibition. Given this research was conducted during the 2012 Summer Olympics only two
libraries made reference to the games; the National Library of Australia had a link to F***y
Durack’s 1912 Olympic gold medal in the library’s Treasure Explorer website, while the. The
National Library of Australia gained its most ‘likes’ to posts relating to ‘Cupcake day at the
national library’.
A feature of all the Facebook sites is that they present a corporate face to the world and there
would seem to be little crossover between the corporate pages and the librarian’s
personal Facebook activity, a distinct difference from Twitter which often blurs the lines
between personal and corporate.
For many organisations Twitter has become their de facto social media presence and is their
primary communications platform. Twitter perhaps better than other platforms exemplifies
the ability to enable a rapid two way dialogue and library use of Twitter suggest this is a
popular platform for reaching out to communities.

Twitter statistics. Figures for Follows, number of Tweets and number of relate to
the period 22 July 2012 – 22 August 2012. The data for Twitter was collected from TOPSY
and TwitterCounter.
Libraries use Twitter for a various reasons, operational issues such as opening and closing
times, or to showcase activities and new additions to collections and responding to questions
and feedback. The way Twitter was used varied greatly across the libraries with some
adopting a conversational approach while others tend to view Twitter as a conventional ‘top
down’ broadcast medium. Twitter because of its fleeting nature lends itself well to a more
light hearted and humorous tone which would be less appropriate for other sites such as
Facebook or YouTube.
The British Library is the only library in the sample which has attempted to personalize the
majority of its Twitter accounts by mentioning by name the individuals behind the account,
presumably to give the impression that their Tweets are not merely news feeds from the PR
There is evidence of the libraries using Twitter to cross promote their activities for example
by the BNE which was Tweeting about the final days of its Gyenes exhibition which was also
heavily promoted on Facebook. This integrated approach to social media is vital to ensure
engagement and the BNE’s success here stands out.
There are imaginative ways of using Twitter with unconventional but engaging content, for
example Orkney Libraries tweeted an entire book one Tweet a day supported by ongoing
competitions, an innovative approach that won the library two GoldenTwit awards in 2011.
The key to success with Twitter is striking the right level between being forced and over
familiar and aloof and distanced from the audience.
All the libraries in the sample have blogs but how the blogs were used varied widely across
the institutions and with the exception of the BNE all the libraries have multiple blogs.

Blog Statistics for 22 July 2012 – 22 August 2012.
The tone taken in blogs varies from the formal to the informal with perhaps the most
impressive activity undertaken by the Library of Congress. The library promotes its activities
through its blogs but the librarians are given a free hand and the personal voice of the author
gives imaginative access to the collections. A caveat confirms the blogs do not represent
official Library of Congress communications. The NLA’s blogs are well explained and give
the chance to see behind the corporate body through blogs such as ‘Page turners, what the
National Library of Australia staff are reading’ and ‘Paddy's kitchen, a recipe blog to
accompany the Patrick White exhibition’ a good example of social media being used in
conjunction with an event.
The long blog posts of the Bibliotheque National de France contains rich links to its
catalogue records and external websites such as Wikipedia, making this blog a useful
resource. Blog posts from the BNE tend to be long, essay style pieces supported by images
from their collections.
It is worth noting that many of the blogs have commenting systems native to the platforms
they were built on, if they integrated Facebook comments or other social media they would
improve their chances of receiving more comments on their posts.
Not surprisingly it is more difficult to post decent quality videos than static images and
statistics for YouTube are varied.

The key indicator on YouTube is the number of subscribers as this shows how much people
like the content and wish to maintain contact with the channel and suggests the library has
built up a following instead of random viewers which indicates better engagement. This can
be promoted with prompts and hints to urge people to subscribe to the channel. YouTube
content ranges from interviews and recorded presentations of full conferences, such as the
BNE’s ‘El libro como universo’ to more practical issues about using the library such as
searching online, taking out books or tracing family histories, an approach the NLA has taken
with its YouTube offering.
The Library of Congress has a huge number of total views, almost 4million but this could be
explained by Google searches pointing to the videos rather than the marketing efforts of the
library itself. For instance a Google search on ‘Execution of Queen Mary’ will bring up the
LOC YouTube video fourth in the results list of LOC. The video has been viewed over
166,000 times.
Other Social Media
In addition to the platforms mentioned it is relevant to discuss other social media which are
used by libraries. The photo sharing site Flickr is widely used by many libraries as it is a
superb channel to display photographic collections. Flickr also allows for some imaginative
use of tagging around adjectives (for example ‘fear’, ‘hope’) which allow for easy
identification of relevant images. Re-use of images of Flickr can vary however and the
wording on some Flickr accounts restricts commercial use whereas the Flickr images of the
NLA are Creative Commons and allow unrestricted use, a strategy also deployed by the
Library of Congress.
Pinterest ( is a relatively new social media platform which was founded in
2010. Pinterest acts like a virtual pinboard allowing users to organise and share images
around themes, hobbies or activities such as crafts or even weddings. No libraries in the
sample are using this platform at the time of writing although there are images of libraries
posted to the site by members of the Pinterest.
In general libraries have adopted a multichannel approach to social media and are using the
familiar household brands we use in our personal and professional lives. There are
differences across the libraries and the libraries are using social media for many purposes,
from marketing and promotion, opening up the resources of the library, and a customer
service function by responding to queries and questions. It is impossible to know what social
media success looks like for libraries without undertaking in-depth research but librarians are
trusted information professionals are well placed to harness the opportunities available in the
world of social media.


The Definitive Media Library & CMDB in the context of the Release Management Process
A Definitive Media Library is a secure Information Technology repository in which an organisation's definitive, authorised versions of software media are stored and protected. Before an organisation releases any new or changed application software into its operational environment, any such software should be fully tested and quality assured. The Definitive Media Library provides the storage area for software objects ready for deployment and should only contain master copies of controlled software media configuration items (CIs) that have passed appropriate quality assurance checks, typically including both procured and bespoke application and gold build source code and executables. In the context of the ITIL[1] best practice framework, the term Definitive Media Library supersedes the term definitive software library referred to prior to version ITIL v3.

In conjunction with the configuration management database (CMDB), it effectively provides the DNA of the data center i.e. all application and build software media connected to the CMDB record of installation and configuration.

The Definitive Media Library (DML) is a primary component of an organisation's release and provisioning framework and service continuity plan.


In a controlled IT environment it is crucial that only authorised versions of software are allowed into production. The consequences of unauthorised software versions finding their way into the live environment can be serious. Typically, in a mature organisation, stringent Change and Release Management processes will exist to prevent this occurring, but such processes require a place where the authorised software versions can be safely stored and accessed. The solution put forward by ITIL in its third version is called the Definitive Media Library or DML (replacing the previously named Definitive Software Library or DSL in version two). ITIL proposes that the DML can be either a physical or virtual store and there are benefits and drawbacks with either method. Clearly, however, there are key factors in the success of any DML solution i.e. software required to be deployed into production should be rigorously tested, assured and licensed to perform and also packaged in such a way that it will safely and consistently deploy. Also, the DML should be easily accessed by those, and only those, authorised to do so. In this way, a virtual (electronic) storage area will almost always provide a superior solution, meaning the DML can be centralised and accessed remotely or outside normal business hours if the need arises (see distribution).


The DML plays a critical role in supporting the transition from development to production phases and DML solutions should be distinguished from other software and source code repositories e.g. Software Configuration Management or SCM (sometimes referred to as Software Change and Configuration Management) that supports the development or software evolution phase. This is an important distinction and often causes some confusion. In essence, whereas SCM tools or repositories store and manage all development versions and revisions of code (or work products) up to but not including the final authorised product, the DML stores only the final authorised versions of the code or product. This is analogous to a high-street product lifecycle where the product moves from design house to factory, through to warehouse and then shop, i.e.

records (metadata) are kept about how a product is designed developed and built. This enables the tracking down of which process is to blame where faulty products are discovered either during quality control or even in later service.
records (metadata) are kept in a CMDB about where the software is installed and deployed from the DML and into the production environment. Each installation or deployment should be authorised by a corresponding production change request and the resulting change recorded in the CMDB as a relationship between the DML artefact and the platform where it has been deployed.
In a more mature or evolved state there is no distinction drawn between the two forms of configuration management and the process is continuous supporting the whole service delivery and service operation lifecycle. This has been referred to as Enterprise Configuration Management. Even here though the development-based artefacts should still be distinguished from and kept separate from the management of quality assured, definitive master versions available for deployment. In an outsourced or multi-vendor arrangement the existence or otherwise of a consistent and secure form of supplier access will dictate whether or not the software configuration management is performed passively (externally by suppliers adopting their own SCM tools and then delivering the finished product) or actively (overseen internally with suppliers utilising the centrally hosted SCM tool). All finished products, however, (application software) in their authorised deployable form should be stored within the central DML.

Typical CIs that a DML will store include:

Packaged in-house application software
Commercial off-the-shelf (COTS) raw media
Customised COTS software (containing enhancements, tailored configuration etc)
Release packages
Patches (see patch (computing))
Gold builds (clients, servers, network and storage devices etc)
System images
Across multiple technology stacks and distribution technologies (e.g. Wintel, UNIX, ORACLE, mainframe, network, storage etc)
Media Release Lifecycle Edit

(see "Definitive Media Library & CMDB in the context of the Release Management Process" diagram above)

The media release lifecycle steps are:

Demand for new service or product arises.
Decision is made to make or buy the product (service, build or application) based on functional requirements extracted from the requirements traceability tool. Product is created or selected from the service/ product catalogue in accordance with architectural design policies (Service Design). COTS product is procured and stored in the DML with asset status ‘procured’. If new, the product is added to the Approved Products Catalogue. In-house created application source code is managed directly in the software configuration management repository.
If COTS product or gold build is being packaged, media is extracted from the DML.
Product is packaged or developed and packaged (in which case add-on functionality is treated in the same way as in-house applications and builds).
Stub records or original baselines are created in the software configuration management tool.
Development code revisions and package revisions are recorded in the software configuration management tool throughout development.
Unit testing is carried out.
Packaging is completed to create the release package.
Product package is quality assured (inc testing, staging and any rework).
Completed media package (build, service or application) is lodged back in the DML as authorised media ready for deployment.
Following Change Management approval, product is released to the estate via the appropriate distribution system with logical installations being recorded via due process in the CMS (CMDB).
DML entities are archived as soon as:
CMS or CMDB indicates that packaged release is no longer in use at any location (a period of grace is required following the last decommission or upgrade to allow for any necessary regressions) and
The DML entity has been removed from the technical or user (service) catalogue as a selectable item


Even though the DML as an authorised store for media implies a degree of centralisation, Local Media Libraries (LMLs) will be required in order to achieve a global model. In this way, release and deployment of physical instances of media can be achieved in country in a timely manner by avoiding constant downloads over the global network. Replication of authorised media in non-prime windows would make required packages available locally as required, but the DML would remain as ‘master’ for process control reasons. The DML/LML hierarchy is synonymous with the master/secondary distribution layers seen within many distribution technologies and package management systems. However, whereas distribution tools tend to be biased towards a particular technology stack (e.g. Wintel, Unix, Mainframe etc), one of the main benefits of a DML is its technology-agnostic nature and a true central store for all authorised software. In this way, the distribution tools would connect to the DML to obtain the software package. Application packaging involves the preparation of standard, structured software installations targeted for automated deployment. Packaging is also required for bought-in (COTS) software, as packaging allows software to be configured to run efficiently on a particular platform or environment. Even a slight change in this platform (such as the swapping-out of disk) can prevent a package from successfully deploying so retention of the raw media (ISO) version of software is critical as this will be needed (often in an emergency) should the packaged version no longer deploy e.g. following the upgrade or replacement of the operating platform.
