Correspondence, checkbook stubs, deposit slips, medical bills, automobile registration, tax forms, mortgage and investment documents, and insurance policies. The income tax folders consist of correspondence with the IRS and records of expenses, including receipts and travel documents. Cowley's original folder titles and organization were retained, with the addition of new subjects such as Home Office, and the division of Insurance into life, medical, and dental.

Original folder titles and comments were kept and placed in the front of the folder, except in cases that lacked an original folder title or comment.
