The Susan G. Casey Art Library was established by Susan's parents, Mr. and Mrs. Dan Casey, following the passing of their beloved daughter. Susan was an art student at Georgia State University. The library was originally housed in the historic Mable House and relocated to the Mable House Arts Center soon after it was constructed. The original library collection was housed in an antique two-door cabinet and a painting by Ann Cockerill hung above. The cabinet and the painting were relocated to the Mable House Arts Center, and three additional bookcases were donated by the Friends of the Mable House.

The Casey Art Library exists for the enjoyment and education of the public. Items in the library circulate to members of the South Cobb Arts Alliance (SCAA), Mable House employees, and persons enrolled in classes at the Mable House Arts Center.

The Casey Art Library collects books, audiobooks, magazines, CDs, VHS, and DVDs with an emphasis on non fiction works. The subject matter of the items collected is related to the arts and/or courses at the Mable House Arts Center. Items are acquired through the donation of funds and materials, and by direct requests submitted to the SCAA board. Donated materials become the property of the Casey Art Library and will be added to the collection or donated to another organization, as the art librarian sees fit. The library cannot add all donated materials due to space limitations and collection scope. Please consider the collection areas before donating materials, and note that donations are tax deductible.
