How Web 2.0 Tools in Medical Librarianship Support Medicine

Slide, video and photo shares can be used to show medical footages, atlases, educational clips in medical libraries, an example of atlases of skin diseases heart operations.
Wikis can be used as an open-source depository of case studies and finally a best source of evidences.

Really Simple Syndication (RSS) gives the possibility of being informed about new items added to the interested site. Librarians can utilize the RSS feeds to catch up trends and changes of desired medical specialty, and simultaneously to give the same opportunity to user community to keep themselves up-to-date.

Blogs can be considered a very useful and good source of information to find information about the trends and debates in specific field.

From the above discussion it can be deduced that:

Web 2.0 is a system in which online users become participants rather than mere viewers.

It Allows dual communication instead of single source information.
Web 2.0 tools are fast making the internet a true democratic system, a digital democracy. Instead of getting information from once source that could have an agenda or could be bias, information is received from multiple sources, making it easier for decisions to be made.

Web 2.0 tools are helping in making the internet more personalized. Everyone has different needs, and it will allow each individual to have information that is tailored to their needs and interests.

Information can now flow freely, and people can express their ideas without fear of subjugation.

Web 2.0 has made communication a lot easier. It has become obvious that the Internet is one of the greatest communication mediums in the world. For example, Cataloguing in libraries is made easier through facebook applications as already seen above.

Problems with Web 2.0

One of the key problems with Web 2.0 is dependence. Some people over depend on the internet that if the server goes down or there is no connection they will have to wait to get their work or assignments done down.
What about students who just copy and paste information from the net.
What of those people who do not know how to evaluate information from Wikis, Blogs, etc
What about the fact that security of information in some of these free service sites is not guaranteed. Hackers can easily get into the system.
What of those people sharing information that is copyrighted? If this information is shared freely how can people generate income?

Thus;
It is for this reason that information literacy is important because someone who is information fluent will know how to give credit to the authors or owners, as such solving the problem of copyrighted material.

Those who are information fluent will be able to find, retrieve, evaluate, analyze, share and use digital information well ( see Digital Information Fluency Model above) They will be able to use web 2.0 tools to make them independent and lifelong learners.
