As part of the reintegration of the traditional and computational lexical research and development activities at the University of Gothenburg, the Swedish Academy's lexical databases are being edited for greater consistency and included in the computational lexical infrastructure of Sprkbanken Text, which in turn is undergoing considerable development in order to meet the requirements of tradi tional lexicography.One aim of this work is to formally interlink these databases with Sprkbanken's Lexical Research Infrastructure.In this chapter we focus on the opportunities for diachronic lexical research offered by the inclusion of one such dataset in this infrastructure.SAOLhist Plus brings together digitized versions of successive editions of the SAOL dictionary, 10 editions covering a timespan of almost a century and a half.Together with some other historical and modern dictionaries and combined with large corpus-extracted vocabularies from the same time interval, we can make wide-ranging and detailed investigations of lexical change in relation to the history of lexicography in Late Modern and Contem porary Swedish.
