The Spencer Heath Series

The Archive, covering the period between 1887 and 1963, is stored in 22 boxes divided into seven series: Articles, Audio, Book (Citadel, Market and Altar), Correspondence, Conversations, Photos, and Subject Files.

This series of approximately 1000 documents includes various items that don’t fit into the other series. The majority of the items are handwritten notes on a wide range of subjects. This series, like the others, is searchable in several ways, but the most useful may be by keyword.

Made up of approximately 1250 letters from 1894 to 2014, about 1100 of the letters are from Heath between 1954 and 1962. Most of the documents are carbon copies of letters from Heath, but there are some original letters to Heath. There are also some drafts of letters composed by Heath.

This series contains approximately 200 articles and essays, written mainly by Spencer Heath and Spencer MacCallum. There are also a few articles about Heath and pieces he found interesting and saved.

This series contains approximately 450 files that are either transcripts of conversations between Heath and his grandson or verbatim notes MacCallum made from such discussions.

This series is related to Citadel, Market and Altar, the only book he published in his lifetime. It includes multiple versions of each chapter and material related to the promotion of the book. It contains around 50 documents.

There are half a dozen photos of Spencer Heath, including one from his youth.

This series is seven audio files of either Heath or lectures about Heath.
