Series 3: Maps and Surveys, 1849-1981 contains originals and copies of maps and surveys of Princeton University land that were intended to represent the campus and other University lands as they existed. This is in contrast to maps, plans and surveys in the records of the Office of Physical Planning, which were created as part of the planning and development process and may or may not represent what actually existed. In addition to professionally produced and published maps, this series also contains several student surveys of portions of university land from the early 20th century, possibly created as part of an academic course.

This series includes some 10,000 letters, telegrams, postcards and other communications received by Russell and his immediate associates over the years 1897 to 1956. The letters are arranged alphabetically by correspondent and then chronologically for each correspondent, with corporate entries and cross reference cards as described for the outgoing correspondence. Russell's colleagues often sought his opinion of their work, and some 175 manuscripts are interspersed with the incoming letters. Folders of correspondence which contain one or more manuscripts are labeled on the right side "Manuscript enclosed with correspondence". At the same time, there is a 3 x 5 yellow card for each manuscript which lists its author, title, length, date, and location. The yellow cards are arranged alphabetically by author in a file stored in the manuscripts catalogue.
