In 1888 when students and investigators arrived in Woods Hole for the inaugural session of the Marine Biological Laboratory (MBL), they recognized the need for a library collection of books and journals. The one wooden building on campus, later known as Old Main, housed everything, with researchers upstairs and the student laboratory downstairs. Lectures were held in one corner, and shelves held what books and journals were contributed. As the first MBL Director Charles Otis Whitman noted in his 1888 Annual Report, having a library was absolutely essential for the success of the lab and would have to be provided somehow. The initial core volumes should include reference works and textbooks, and also the important journals in the four languages thought to be essential at the time.
