I keep searching the Internet for new information on digitization, especially "how to" items. Today I found a link to the Mississippi Digital Library Program Digitization Training Manual.
Several libraries in Mississippi are cooperating on an IMLS funded project to "make civil
rights materials from a variety of archival repositories available to a wide audience by
means of computer access." Information will be captured using scanning, optical character
recognition (OCR), and transcription.
The 40-page manual is undated, but seems recent given that the introduction refers to the current grant. It is worth perusing to see if you can learn from what they are doing.
