The SALAMANCA CORPUS has been conceived as an electronic repository of diachronic dialect material which might bridge some of the gaps still existing in the field of English historical dialectectology. It consists of documents representative of literary dialects and dialect literature. It aims to cover a time span of no less than four centuries (c.1500-c.1950), thereby presenting documents in which dialect traits from pre-1974 English counties are documented. Some of the texts supplement the monumental primary sources of the English Dialect Dictionary (1898-1905), thus adding to our understanding of old regional speech. The compilation follows the pluralistic stance that has recently been adopted by diachronic linguistics, seeking to provide a democratic account of non canonical literatures too.
