Eighteenth Century Collections Online (ECCO) is a digital collection of books published in Great Britain during the 18th century.[1][2]
Gale, an education publishing company in the United States, assembled the collection by digitally scanning microfilm reproductions of 136,291 titles.[1][3] Documents scanned after 2002 are added to a second collection, ECCO II. As of January 2014, ECCO II comprises 46,607 titles.[4]
'The microfilm images are digitized using software developed by HTC Global Services in Troy. The cost per image has declined from 16–19 cents to below double digits' said CEO Allen Paschal.
