In order to achieve the objectives of the e-Humanities framework, it is necessary for individual humanities fields to take charge and to create their own specific techniques that apply to their own unique varieties of data. The e-Linguistics Toolkit is presented to aid the move of linguistics into this new digital era. We show that achieving this requires data interoperability in terms of encoding, format, and content. Once data are made interoperable, data manipulation in the form of validation and merging is necessary. As one way to ensure immediate usefulness to the ordinary working linguist, the toolkit offers data transformation services among various working formats and lays the foundations for intelligent search.
