The largest portion of correspondence is with Charles Edwin Bessy on botanical matters, including botanical publications in the United States and Europe, and plants and shell specimens.

This is a miscellaneous collection of letters, and a few documents, concerning botany, gardening, agriculture, Darwin and evolution, and the herbarium at the University of Edinburgh.

Correspondence compiled by Edward E. Wildman and Francis D. West, chiefly from original letters in the Historical Society of Pennsylvania and other depositories, 1956.

This microfilm contains letters and drafts of replies, memoranda, lists of plants and shrubs, observations on natural history, diary notes, extracts from reading, and recipes. There is a "Catalogue of Books given to [Friends] Publick School of Philadelphia" by Collinson dated 1749. There is a copy by Collinson of a May 16, 1560 note by Elizabeth I of a gift of old clothes to her maids of honor. A 1811 letter is from C. S. Collinson to Aylmer Bourke Lambert.

Principally covering botany and agriculture, this collection includes many manuscripts on trees, shrubs, and plants of different species, copies of botanical essays by others, essays on fruit trees, etc., by Auguste Denis Fougeroux de Bondaroy (1732-89), notes and drafts for the latter's revision of Duhamel's Traité des Arbres et Arbustres.
