For anyone who remembers studying Latin the old way, constantly paging through a dictionary, these electronic texts are a revelation.
"Google Books is now assisting by sharing high-resolution digital scans of over 500 volumes of Ancient Greek and Latin, dating 16th through 19th centuries. Jon Orwant and Will Brockman created this collection using a list of several thousand important Classics volumes identified by collaborators Professor Gregory Crane and Alison Babeu of Tufts University. We're analyzing additional volumes and expect to be able to release more high-resolution scans in future," noted Google.
These scans will aid development of accurate OCR algorithms for Ancient Greek, and provide basis for electronic versions of important editions of these Classics texts; but perhaps their greatest value will be for development of new methods in this emerging field.
