ECCO-TCP resulted from a a partnership with Gale, part of Cengage Learning, to produce highly accurate, fully-searchable, SGML/XML-encoded texts from among the 150,000 titles available in Gale’s Eighteenth Century Collections Online (ECCO) database.
Eighteenth Century Collections Online includes significant English-language and foreign-language title printed in the United Kingdom during the 18th century, along with thousands of important works from the Americas. The database contains more than 32 million pages of text and more than 205,000 individual volumes in all. In addition, ECCO natively supports OCR-based full-text searching of this corpus. This is significant because it meant that unlike EEBO-TCP (which produced searchable text where there was previously none at all), ECCO-TCP could only hope to produce more accurate text (and more reusable text) than what was already available. The larger size of ECCO (because of the great increase in printing and greatly enhanced chances of survival of printed works in the 18th century) also made it a different proposition: nothing so ambitious as EEBO-TCP coverage was feasible for ECCO-TCP.
