[Harold Wolfe mounts boards for the Current List of Medical Literature]
Image caption on page 47 of the book US National Library of Medicine: "Harold Wolfe mounts boards for the Current List of Medical Literature, ca. late 1940s. Citations were typed on regular sheets of paper, which were then trimmed and pasted onto the boards. Paste jars and thinner are on the desk. The completed board was photographed on high-contrast lithographic film, which also reduced its size to a more standard page, and printed via high-speed offset lithography. This was a fast, efficient, and relatively inexpensive way to produce these time-sensitive volumes."
