The Iowa Women in Natural Resources records date from 1987 to 2007 and measure 5 linear inches.  The records are arranged in six series: History, Conferences and programs, Directories and membership lists, Minutes, Newsletters and correspondence, and Publicity.

The History series (1987-1988 and undated) consists of a copy of the initial action strategies for IWINR compiled at the first state conference and drafts of the articles of incorporation used by IWINR to become an official state chapter of Women in Natural Resources. The Conferences and programs series (1987-2002 and undated) contains information and programs from each of IWINR's annual conferences from 1987 to 2002.  Included are videocassettes of selected programs presented at the conferences.  Also included is information about the community projects with which IWINR was involved, such as the "Outdoor Journey for Girls" and "Outdoors Women" projects.
