Here's an excerpt from the project home page:
After more than twelve developer years of design and engineering and over two million USD of investment, the Specify Software Team is delighted to release today, April 10, 2009, Specify 6 for Windows, Mac OS X, and Linux desktops.
Specify is a client-server database platform for museums and herbaria which processes specimen information for computerizing holdings, managing collection management transactions, and for mobilizing species occurrence data to the web. Specify is free and open source software licensed under the GNU GPL2. Downloadable installation packages for all three desktop flavors as well as Specify's Java source code are linked to this site. . . .
Non-profit U.S. research collections are eligible for our helpdesk and data conversion services thanks to our financial support from the U.S. National Science Foundation, Division of Biological Infrastructure. We look forward to working with you to increase the research impact of your institution's investment in biodiversity collection curation and specimen data management.
