By J. W. Hill. Some studies of the library use of journals show that biological scientists, including ornithologists, also consult the older journals more frequently than most other scientists. Studies in avian systematics, bird populations, evolution, and behavior, to name a few areas, are all based on observations and reports made over a long period of time. Mann Library maintains as complete coverage as possible of current serial publications relating to ornithology. Journals dealing solely with birds are supplemented by those covering the wider worlds of animal physiology, behavior, conservation, ecology, systematics, etc.
Coverage is international and journals of substance in many languages are included.
For the majority of journals, particularly those in which English is a major language, the library's holdings date back to the beginning dates of publication. It includes regularly or irregularly issued transactions and reports of ornithological conferences, annual reviews, certain periodicals for the amateur ornithologist, and major monographs numbered as issues in a series. In all, through subscription or exchange, Mann Library currently receives some 200 serials classified in the field of zoology, of which about 75 specialize in ornithology. Also available are another hundred or more serial publications in ornithology that are no longer published. Mann does not attempt to collect the many locally-oriented newsletters and magazines issued by bird clubs across the nation.
