Borrowing This service is available only to officers and graduate students of Harvard's Department of Organismic and Evolutionary Biology. Interlibrary loan request forms are available at the Circulation Desk, and may be left there or with the Interlibrary Loan Assistant. The Ernst Mayr Library lends books and provides photocopies to other libraries and institutions, subject to the policies below. If more than one title is requested simultaneously, each work is considered a separate transaction. Unless the borrowing library indicates otherwise, photocopies are substituted automatically on all such requests.
All books are to be used only in the building of the borrowing library.
