The book deals with the appropriate application of the computer by textual critics, grammarians, exegetes, (Bible) translators and theologians. It contains directions for educational purposes and editors of journals and texts, the collation of mss and new projects are demonstrated. The computer can assist the researcher variously; by putting him/her in the position to deal with large corpora of data. Basic research can thus be executed more readily. Powerful search programmes such as Quest II are explained. The results of more sophisticated programming are demonstrated. Not just the micro unit, the lexeme, can be studied, for semantical purposes, but also the macro picture, such as syntactical structures. Finally the book deals with methodological issues pertaining to the appropriate application of the computer. Users are warned against unreflected use of computers.
