Series II. Reference Materials Associated with Index Cards, 1776-1986

The following subseries were organized as distinct collections by the employees of the Office of Fiber Investigations. Each collection has an abbreviated code which appeared on index cards in the Dewey Index (Subseries I.A.) and Reference Cards (Subseries I.B.).

The textile samples that comprise this subseries were sent by Testfabrics, Inc. to librarian Kate Hayes, Fiber and Textile Information Center at the National Agricultural Library (1986-1990) for a textile testing project. Hayes used the USDA Crop Fiber Research Collection as a resource for her work.
