The Carrie Baily Aaron papers collection is comprised of Letters, a notebook, photographs and illistrations. The three letters are signed by Aaron, Carrie B. 1910; Skinner, Henry, 1890; Wood, Harold Bacon, 1955. The notebook contains an entomological essay by Mrs. Aaron. The essay was entered in a contest and won the prize offered by Robert H. Lamborn. This collection also contains portrait photographs of Dr. Robert H. Lamborn, which were held in collection 457 until they were returned to their original context. This collection also contains Lepidoptera illustrations, which were originally accessioned along with the other materials but made into a separate collection 911 for some reason. They have been returned to the context in which they came, and include:

An original watercolor of American moths labelled: Copied from Nature by a lady, 1814 to 1815.

A Lithograph of Lycaena II labelled: Drawn by Mary Peart, Bowen and Co., Phila.

Researchers should note that these illustrations are oversize and therefore housed separately from the rest of the collection
