Their motivating examples were in domains such as optical character recognition and handwritten zip code recognition, in which the primary concern is that of learning the typical variations characteristic of a class of objects and separating

In this sense the book represents a new kind of historiography: history based on optical character recognition, allowing a rapid “combing” of the archives for historical gems (and fleas).

for terms like “cancer” or “nicotine” turn up hundreds of thousands of documents. Searches for terms like “baseball” or “sports” yield many thousands of hits. Optical character recognition was introduced in 2007, which means you can now search for expressions like “please destroy” or “subjects to be avoided,” with options to order the

is wonderful about the seventy million pages of documents now online at http://legacy.library.ucsf.edu is that they are full-text searchable by optical character recognition—which means you can search a term, or string of terms, and obtain (theoretically) every document in which that term or string appears.

1973, we spent years training a set of research computers to recognize printed letters from scanned documents, a technology called omni-font (any type font) optical character recognition (OCR). This particular technology has now been in continual development for almost forty years, with the current product called OmniPage from Nuance. If you want
