This Accession Item is a photocopy set of the pages from my MRC-JVM Lab Book #4; the entries beginning on March 3, 1960. The Archival DVD Folder of the same name contains only a JPEG-Image scan of the cover of the spiral-bound original, and a few additional scans of dated pages. The photocopy set of the entire contents is provided in a 3-Ring Notebook binder. Note: Although the cover of the original notebook shows the entries extending to September 22, 1962, the most recent date found is February 7, 1961 - thus pages may have been removed long ago, or else there is a recording error
