November marks two milestones for TSZB. This is both the final print issue as well as the first online, open access issue of this journal. The print version has finally succumbed to the challenges we have faced sustaining funding for printing and mailing this predominantly exchange-based periodical. With this issue, we are changing the format of TSZB to ‘Open Access’. The contents will be available for download free-of-charge via the Internet. We will continue selling reprints and  complete back issues to anyone wishing to have these until our supply runs out. Individuals and institutions interested in obtaining back issues should visit: http:// www.museum.tulane.edu/publications/tszbback.shtml. PDF’s of scanned back issues of Tulane Studies in Zoology and TSZB can also be obtained without cost from the Biodiversity Heritage Library (http://www.biodiversitylibrary.org/title/5361).
