DFC Proceedings are available in pdf format from Volume 1 (1969) to Volume XXXIX (2007) below. Some pdfs contain multiple years and are so designated. The Compiled Proceedings of the Desert Fishes Council from 1969-2017 can be found as a PDF here: https://repositories.lib.utexas.edu/handle/2152/68639.
As discussed during the 2013 Business Meeting, the Proceedings Editor and Webmaster are working to update the online content and convert the Proceedings from the historic format of annual bound issues to an online, searchable database of presented abstracts.
