This sub-series consists of all manner of notes and a variety of secondary materials gathered by Lewis as he researched the life of his grandfather. Secondary materials include historical publications, photocopies of reference works, scientific article reprints, and newspaper and magazine clippings. These series also contains dubbed copies of taped interviews with Penfield obtained by Lewis through the CBC, as well as transcripts of these interviews and others conducted by Lewis in the course of preparing the biography.

This sub-series consists of various drafts of Something Hidden. The drafts are not always easy to distinguish in terms of chronological sequence, but an effort was made during the initial processing to roughly order the drafts by version and divide them by chapter. Also included are notes for additions and deletions, labeled “Adds and Outs.” At times, some research notes and primary Penfield material are interfiled with the drafts. This series also includes a draft of the screenplay for the film.

This sub-series contains one small red leather pouch with “H. Lewis” written in pen on the interior and one empty metal frame included in the original donation and accessioned with the rest of the collection.
