What does it mean to be a science librarian 2.0?

Science librarians, as well as other librarians, have seen ample new technologies come and go over the years. Librarians experiment and try to find ways to employ the new tools in our libraries.

This paper discusses what technologies have proven to be successful, as well as other thoughts to bear in mind as librarians evaluate Web 2.0 tools for science libraries.
