"The CERL Thesaurus File is a unique facility developed to address the particularly European issue that place name and personal names in Europe varied from country to country in the period of hand press printing (1450 - c. 1830). The CERL Thesaurus file contains forms of imprint places, imprint names, personal names and corporate names as found in material printed before the middle of the nineteenth century - including variant spellings, forms in Latin and other languages, and fictitious names."
