Max Kovel obtained the pdf files used by the publisher for the
Yearbook. This consisted of several smaller files.Thanks to the
hard work of Lou and his son-in-law John C. Loudon the complete Yearbook has been
assembled and is now available on-line with a query capability.

At my request Lou provided an email describing the evolution of the Digitized Yearbook over the years.
