The Allin Brothers Field Books Collection (1887-1940) is part of the Field Books Collection, which comprises about 400 small leather-bound notebooks, which contain field records of the Pasadena City Engineer. This supplements a smaller collection of field books received earlier from the Public Works Department, which relate mostly to Pasadena's parks.

Brothers Thomas David Allin (1864-1942) and Charles Arthur Allin (1867-1940) founded the Allin Brothers civil engineering firm, which was located in the Boston Building in Pasadena, California. The Allin Brothers civil engineering firm was responsible for first laying out and building many of Pasadena's streets, sewers, parks, bridges, and other civic structures.
