The lexicographer Herbert Andreas Welker's book of more than 500 pages about pedagogical lexicography provides a panoramic overview of the various types of pedagogical dic¬tionaries as well as the corresponding theoretical literature. Welker's method is descriptive, with himself mainly an observer of lexicographical practice and a "collector" of — frequently opposed — opinions and ideas expressed by a large number of scholars. This method allows the reader to become acquainted with an important part of the most relevant literature on pedagogical lexico¬graphy which is presented in a systematic and condensed form. Written in Portuguese, the book might perhaps not be so easily accessible to many readers. This review article provides a guided tour through the main contents of this highly recommendable book and discusses some of the most important ideas reproduced in it.
