content: This series is divided into six subseries: Subseries 4.1: #1-#4108, 1947-1961; Subseries 4.2: A1 to A400, 1941-1949; Subseries 4.3: B1 to B9995, 1953-1963; Subseries 4.4: C1 to C6999, 1963 [1969?]; Subseries 4.5: Chronological, 1950-1955; Subseries 4.6: Topical, 1941-1961. The negatives are approximately 4" x 5" and are housed in glassine envelopes. In some instances, 4" x 5" prints are filed behind the corresponding negative.

The alpha-numeric negatives are not complete. There are indices (see Series 3) for the negatives in boxes 36 to 38 and the logbooks (see Series 2) maintained by Richard R. Angelo. The indices provide the alpha-numeric identification number, date, and brief description for the negative. For example, negative B-528 documents the #4 mine machine shop looking west, March 12, 1954. Researchers should use the logbooks in conjunction with the negatives.

There are some negatives that document diagrams, drawings, plans, sectional views, schematics for ore pockets, mine shafts, and flow sheets for the Lebanon Concentrator and the crushing plant at the Grace Mine. Some of the negatives were used in the creation of the Bethlehem Mines Corporation, Cornwall Division, photograph album which documents progress as of December 31, 1964.
