Consists primarily of correspondence and printed material, along with two diaries from 1926 (one kept by Marian Holden, and the other kept by Alice Holden), a matted postcard, a photogravure plate of E. B. Holden's portrait and signature, and a piece of hair jewelry (likely made of hair from her aunt).

The correspondence consist of letters between members of the Cort family, or letters to Alice Holden from her children. Most of the Cort family correspondence is addressed to Mr. and/or Mrs. N. L. Cort (Nicholas Leonard Cort or Amanda Hall Cort née Peckham), and the majority of the letters are from their children, including Alice. Some notable threads in these family letters include business correspondence between N. L. Cort and his son, Clark, as well as letters between Amanda Cort, her son Mortimer, and her cousin Mary, with whom her son was staying for a period of time. The letters to Alice Holden are from her children: some of the letters are from when her children were very young and include drawings, but the majority of the letters are from her eldest son, Arthur Cort Holden, between 1907 and 1919. A small amount of correspondence relates to donations made to the Grolier Club between 1920 and 1978 by Alice Holden, Marian Holden, and Jessie Lawrence (née Cort, Alice's sister). In addition to the correspondence are poetry, prose, an insurance policy note, and a few recipes. The printed materials in the collection consist primarily of book catalogues, documenting some of the dispersal of E. B. Holden's book collection in the auctions and sales conducted in the years after his death.
