One of the largest library gatherings (other than the ALA meetings) is the TLA meetings. Texas is a big state, and we've got a lot of librarians.
This year, fortunately, we aren't displaying at TLA. This gives me more time to get ready for our debut at BEA. But I am going to go with a contingency of Austin authors to walk the exhibit hall floor and look around. I'm looking forward to the opportunity (and the free stuff). There won't be as many freebies as there used to be, but I have high hopes for some good stuff -- especially reading guides.
