Numbering Codes

To keep track of his work, Horydczak gave a sequential number to the negatives he took for each of his photographic jobs. Later in his career, he selected what he considered the negatives most likely to sell as prints and gave them a new number based on an alphabetical subject classification scheme that he devised. The Library has retained his original numbers as part of the current call numbers. For example, the call numbers for these two cherry blossom photographs indicate their chronological or special subject context

"LC-H814- 1898-002" is negative "2" in job "1898" (taken in 1934) and is an 8x10 in. safety negative
"LC-H812- B05-012" is negative "12" selected for the "cherry blossom" (B05) category and is a 5x7 inch safety negative

Horydczak's logbook, arranged in job number order, provides job titles. Dates and commissioning agents are sometimes included. Multi-volume notebooks provide item numbers, item titles, and some dates for the special subject images with alphanumeric numbers. A set of 5x7 index cards provides access by subject. These materials are in the P&P Supplementary Archives. The logbook is also available on microfilm (LOT 11504).
