Day by day count of trays selected and photographed
Sample 1
| Date | No. of Trays | No. of Cards | Cover |
|---|---|---|---|
| 2/3 | 40 | 4,901 | A - Cam |
| 2/4 | 36 | 5,190 | Cam-Dow |
| 2/5 | 35 | 5,285 | Dow-Eva |
| 2/6 | 32 | 5,003 | Eva-Gen |
The number of trays, which may be expected to be processed daily by one photographing crew varies from 30 to 55, depending upon the contents of each tray, the frequency of the occurrence of main entries, and upon the number of hours worked. Likewise the total of cards photographed daily varies. To illustrate one of these influencing factors, that of tray contents, the heading Europe is cited. Here, although the majority of entries are subject entries, there must be followed the same careful process of a card by card examination which may produce only two or three main entries.
Film record
Sample 2
University of Nebraska Library
| Reel No. | Film No. | Section Covered | No. of Cards | Date Mailed |
|---|---|---|---|---|
| 1. | 1. | A-Barq | 5,200 | 2/3/39 |
| 2. | Barq-Car | 5,188 | 2/4/39 | |
| 2. | 3. | Car-Eva | 4,988 | 2/5/39 |
| 4. | Eva-Gen | 5,003 | 2/6/39 |
This record not only keeps a daily account of work done, but also records the daily “incorporation” of film on the project. The two records answer the [p.B-2] question of the number of trays processed daily and serve as a check on the portion of the catalog covered both by day and by each film, of which two or more 100’ lengths frequently are used in one day’s operation.
