I just got this via email, that might be of interest to you:-
This is our official call for presentations for the Library 2.011 conference, November 2 - 3, 2011. The conference will be held online, in multiple time zones over the course of two days, and will be free to attend. We encourage all to participate, and ask that you share this information where appropriate. Presentation submission instructions are at http://www.library20.com/pages/call-for-proposals.
The Library 2.011 conference will be a unique chance to participate in a global conversation on the current and future state of libraries. The conference strands are at the bottom of this email. Session proposals will be posted on the conference website, and we encourage making comments to and connecting with others based on their session proposals, as well as "voting" for session using the "like" button on the submissions. Session proposals are due September 15, and session acceptances will be communicated by September 30.
