[Corpora-List] Eighteenth century corpora

Hi, I'd be interested in hearing about any corpora containing eighteenth century English, beyond what's on the English Historical Book Collection (Gale Cengage’s ECCO-TCP – 2473 titles printed in the United Kingdom between the years 1701 and 1800 and Readex’s Evans-TCP – 5007 books published in America during the years 1639–1800.) Many thanks! Claire Etty Senior Editor (Research), Lexicography Oxford English Dictionary
