Abstract
A range of techniques has been developed for the correction of misspellings in machine readable texts. Discusses the use of such techniques for the identification of words in the sixteenth and seventeenth century titles from the Catalogue of Canterbury Cathedral Library that are most similar to query words in modern English. The experiments used digram matching, non phonetic coding, and dynamic programming methods for spelling correction. These allow very high recall searches to be carried out, although the latter methods are very demanding of computer resources
