Henriette D. Avram; Transformed Libraries

An Obituary For Henriette D. Avram, whose far-reaching work at the Library of Congress replaced ink-on-paper card catalogues and revolutionized cataloguing systems at libraries worldwide, died April 22 of cancer at Baptist Hospital in Miami. Mrs. Avram, 86, had recently moved to Florida from her home in California, Md.

The practical effect of her complicated mathematical formulations was to make library collections more readily accessible to scholars and the general public. Her work greatly expanded interlibrary loan programs throughout the nation and allowed people to sit at computers and look through automated card catalogues at libraries everywhere.
