LISWiki. If you are familar with Wikipedia or Wikis, you will be happy to hear that someone is trying to start a wiki dedicated to library science.
If you are not familiar with the concept of a wiki, I present you with Wikipedia's definition, "A wiki (pronounced [wɪkiː], [wiːkiː] or [viːkiː]; see section Pronunciation) is a web application that allows users to add content and their own version of History, as on an Internet forum, but also allows anyone to edit the content. The term Wiki also refers to the collaborative software used to create such a website (see Wiki software)."
There is a not a lot here yet as it only was started in late June. Looking at the recent changes pages, it looks like most days are seeing 10-20 edits. If enough librarians take interest, this might become a good resource.
I have completed a few edits at LISWiki. I need to create an account. It could be fun if the community can avoid edit wars and keep the spambots out.
