The University of Michigan and Thomson-Gale are cooperating in a Text Creation Partnership to create 10,000 accurately keyed and fully searchable SGML/XML text editions from among the 150,000 titles available in the Eighteenth Century Collections Online (ECCO) corpus. ECCO is a significant collection of titles relating to the history of eighteenth century Britain, and the Text Creation Partnership seeks to create enduring digital text editions of the most frequently studied works. Gale is producing digital page images and searchable OCR (Optical Character Recognition) for the overall collection. The standards-based editions created and owned by Text Creation Partnership will link directly to the corresponding Gale page images and will provide a research and instructional tool of enduring scholarly value.
