This document discusses the concepts of Library 2.0 and user-generated content. It provides two examples of how libraries can incorporate this type of content: 1) Wikipedia and library name authority files, where metadata from Wikipedia entries is linked to library catalogs, and 2) Wikisource, a Wikipedia sister project containing freely accessible source materials. The document also discusses social tagging as a way for users to classify and organize information using freely chosen keywords. It concludes by encouraging libraries to embrace these new forms of user contribution and to build platforms that support collaborative work between librarians and users.

17. Results of the
Cooperation
Over 22.000 link articles
A lot correction wishes for the PND
Wikipedia a good starting point for a
search
Wikipedia users can very easy
become library users

18. Classification of
Wikipedia
via Social Tagging = categories
Thoughts about classification with:
DDC (not free!)
RVK (only uses in Germany )
Basisclassification
UDC (not free, too)
Vision: A free classification for the net

19. 2. Example - Wikisource

20. Wikisource
• Sisterproject of Wikipedia
• Choosen Sources:
• Interesting and specials sources
• which are not aviable in full test

23. Metadata
• No bibliographic standards
• Goal: cooperation with libraries
• Idea: Downloadable metadatas

24. Social Tagging

25. What is a tag?

26. Social tagging
• lot of services eg. del.icio.us connotea,
Library Thing, citeUlike
• see how other taged a resource
• see which resources others taged with a tag
• find others who are interested in the same
field

28. Conclusions

29. UGC: New Tasks?
Who is sorting this?
Who can be a filer?
We can, and we should!

• Libraries have to build the platform
• library 2.0 = team up libraries & user

31. What shall we do?
• Be open for user contribution
• Be ready to share
• Become a librarian 2.0

32. IFLA 2.0?
• Starting up a Special Interrest Group:
