Electronic publications are not accessible without technical aids and need constant, time consuming attention; a look back at the data media and data formats utilized in the past 25 years illustrates this. Recently, an increasing number of conferences and studies address the problem. Use of standard data formats, media and platform independence of data, as well as data centering instead of process centering are requirements for long-term availability. For the humanities, texts are not only the sources of information but also (...) objects of scholarly investigation. Therefore publication in a presentation format only is not sufficient. In addition to more sophisticated tools for analysis, search and navigation, a form of publication is required which does not focus on layout but gives easy access to the content and structure of the published document. Both for the creation and the scholarly evaluation of such documents, tools are required which offer additional functions compared to those provided by commercial publication and access tools. The necessary flexibility is guaranteed by the provision of basic functions of text data processing which do not anticipate or preclude any particular questions. This is illustrated by examples for the evaluation and preparation of digital texts. (shrink)
