Last year, the University of Illinois Library and the Chicago Field Museum submitted a successful grant application to The Consortium of Academic and Research Libraries in Illinois (CARLI) to digitize approximately 175 volumes on the taxonomy and biology of Hymenoptera, the third largest order of insects that includes over 108,000 species of bees, wasps and ants. Biodiversity researchers from several institutions in Illinois are working on Hymenoptera, including the Field Museum, Illinois Natural History Survey, Northern Illinois University, University of Illinois at Urbana-Champaign, University of Illinois at Chicago, and Western Illinois University. Easier access to what is already known about these insects can only improve their ability to understand hymenopteran biodiversity. Some of these books contain very attractive hand-colored plates and so traditionally have been locked up to preserve them from theft. Digitized copies of these volumes, which will also be contributed to the Biodiversity Heritage Library Project, will make these images much more useable and discoverable.
