Series 1 primarily consists of inquiries received from other institutions. Series 2 contains personal correspondence of Helen Gilkey. Series 3 consists of lists of exchange specimens sent to and received from other institutions and individuals. Series 7 & 8 consist of correspondence regarding plant specimens sent or received by the Herbarium.
An addition to the collection (Accession 2005:057) consists of materials pertaining to the collection, documentation, and management of OSU Herbarium botanical specimens. The bulk of this transfer is made up of field notebooks and records generated by the various collectors of these specimens, some of whom originally worked with and collected the plants for the Herbariums at Willamette University and the University of Oregon. These notebooks and plant collection data are arranged and described in the inventory by the name of the collector/botanist. Ledgers maintained by the Herbarium that track the receipt, lending, identification, exchange, removal, and mounting of botanical specimens are also included among these records. Materials generated by the University of Oregon and Willamette University Herbariums before their closure can also be found in this transfer.
