Series II. consists of research notes, proposals, drafts, published volumes, book reviews, and other materials related to Erdoes's written works, as well as written materials by other authors which came to be in Erdoes's possession.
This subseries consists of poems, manuscripts, proposals and other unpublished works by authors other than Richard Erdoes. Many of the authors were correspondents with Erdoes, and their work may have been submitted to Erdoes for review or as a token of friendship. Other materials appear to have been collected by Erdoes as part of his research about American Indians.
