The Mollusk Division Library is one of six divisional libraries in the museum maintained by the University of Michigan library system. The Division library itself (Rm 1019) contains holdings catalogued and maintained by the U-M Library System, as well as books and reprints which are the property of the Division. This includes all of the malacological journals (each set complete), about 1,500 other volumes dealing specifically with mollusks, and many reprints. Additionally, the central Main Room (Rm 2500) of the Museum library and the University's library storage facility houses nearly all existing journals on natural history (i.e., those not dealing specifically with mollusks, but which contain many malacological articles), and the Graduate, Undergraduate, Biological Sciences and Medical Libraries (all less than three blocks away from the Museums building) are outstanding in their coverage of all biological subjects. The entire catalogued U-M library holdings can be accessed by any computer over the university's MIRLYN on-line catalogue.
