The correspondence and personal effects series is composed of the more personal materials in the collection, including letters from friends and family, items owned by different members of the family, as well as biographical and autobiographical information.

The graphic materials series is somewhat wide in its scope, with materials from around the 17th/18th century all the way through WWI. Included are a picture postcard, a book plate engraving, an etching, and photocopies of artist Ernst Kirchner's famous depictions of Dr. Oskar Kohnstamm. While they do not share much in common thematically, together they show the nature of the visual materials the family saved over the years even through a number of moves.

While members of the Kohnstamm-Reich-Hayman family often wrote or were featured in short articles, the books and print publication series puts together the bound volumes in the collection that were either written or collected by a member of the family.

The photographs series contains a small number of portraits and other snapshots of the Kohnstamm-Reich family. Included are posed portraits of those in the family who were drafted into World War I, other more casual portraits, and those of close friends.

The misc. articles and ephemera series contains both articles written by members of the family as well as those concerning them. The series includes scientific writing, articles about Ernst Ludwig Kirchner (who had stayed for a time at Oskar Kohnstamm's sanatorium), and other miscellaneous writing and clippings.
