From the TLA Conference Overview page:

New for 2008, in an effort to help the environment and eliminate the problem of never having enough handouts available, the TLA staff will no longer prepare or ship paper handouts for conference sessions. Program speakers have been encouraged to prepare electronic handouts and submit them to the TLA Office for posting on the TLA website. An index of the 2008 handouts will be found at www.txla.org/conference/handouts.html beginning April 1, 2008. Additional handouts will be added as they are received. Attendees will be able to download the program/session handouts before or during the conference if they want to have them on hand during the presentations. Printers will be available in the Internet Room if downloading to a personal computer is not an option.
