A typescript finding aid was compiled circa 1965 when the Folgers' papers were arranged and described by Folger staff. The introduction to that finding aid is as follows:

The records of Mr and Mrs Folger which are in the Folger Shakespeare Library are only part of those which they must once have had. Certain kinds of papers, like the collection of booksellers' bills and receipts, have probably survived in their entirety. Others, like certain personal bills and letters, only sporadically. Mrs Folger sent ten cases of her husband's books and papers to the Standard Oil, Company of New York in June 1932. Many of the documents now in the library were deposited before Mrs Folger's death; a battered label bears the note “Mr Henry C. in Folger. Cancelled checks; receipted bills, miscellaneous unsorted papers and scraps. These were removed from the closet in the cataloging room on September 26, 1935". More were added after Mrs Folger's death. Some, of the photographs were received from the estate of Mrs Folger, April 7, 1936. A.S.W Rosenbach, presented 3 scrapbooks made by Mr and Mrs Folger during their college days, Sep. 22, 1939. E.J. Dimock, a nephew,presented 2 notebooks and one scrapbook, Oct. 12, 1939. Miss Myers gave E.J. Rogers' correspondence with Mrs Folger, Sep. 22, 1960.

The collection of records which thus found its way into the library had very little order and lay as a miscellaneous collection of crates, boxes, cartons and volumes. The present arrangement is by and large an artificial one. The bills and receipts for books which complement those in the catalogue office were abstracted and filed alphabetically by bookseller and were not included in this list. Plans of the building and certain printed works were added to the main collection. The rest of the collection was arranged as described below. Two groups were deliberately broken up. Among the personal correspondence were many programmes, invitations, tickets, subscriptions…which were placed in other categories. The subscriptions were filed with the financial records and any bulletins, correspondence, invitations…relating to the organizations to which Mr Folger subscribed filed with these subscriptions. Invitations to organizations of which Mr Folger does not ever appear to have been a member were filed with the personal correspondence. The scrapbooks ( - March 1913), except for the three early ones, and loose collections of scrap material which continued the series (1913 - ) were dismantled. Much loose material of a later date had been inserted and was so similar to other papers in the collection that it seemed better to rearrange it. The contents of all, apart from the three mentioned, had been listed by Mrs Folger and most of her lists are extant. Each item had been given a number and for the earlier scrapbooks this numbering started afresh with each volume, but in the later ones the numbers continued from one volume or group of papers to the next. These lists often give one a clue as to the date of a document. They also show that some are missing, particularly the illustrations.

Mr and Mrs Folger accumulated a large number of newspaper cuttings. They subscribed to several newspaper clipping agencies besides cutting out articles themselves. Not all have survived. The duplicate copies were removed; those which had some bearing on the Folgers, their friends and contemporaries, or on the library were listed. The rest, chiefly on the theatre, Shakespeare and Shakespearean studies, were added to the collection of scrapbooks in the main collection.

There is a box (unnumbered) of miscellaneous working papers at the end. It includes a partial index of persons mentioned in the list.
