In April 1995 the IUIS signed an agreement for the University of Maryland's Albin O. Kuhn Library to act as a repository of the Union's archives. The Library also holds the archives of several large professional organizations with related interests: The American Association of Immunologists, the American Type Culture Collection, the American Society for Cell Biology, the Society for Developmental Biology, the American Society for Microbiology, and the American Society for Biochemistry & Molecular Biology.

The records of the IUIS currently occupy about 16 linear feet in some 39 boxes. They currently cover the period 1966 - 2000 and document the origins of the Union, its growth in membership and committees and the development of the International Congresses of Immunology. These records have been organized into five series: Officers and Council, Membership, Meetings, Committees, and Affiliated Organizations.

The Library provides safekeeping for the files, has organized the files, and completed a "finders guide" (directory) which is now available on the internet:
