With a few exceptions, unpublished studies were excluded. If you have not yet done so, please read the information on keywords below before searching. It will make your searches more efficient and productive. The classification by keywords requires some explanation. Although keywords are written without accents or other diacritical marks, such characters are used wherever possible in authors' names and the titles of articles, books, and journals.
Searches are case insensitive.
Comments from users about the substance of the list, including corrections and suggested additions of published scholarly works, will be gratefully received. Decisions about whether to add titles to the list will be made, for the most part, only after the titles have been examined by one of the compilers. A revision of the list is planned for fall 1997, to be followed in the future by annual revisions. Implementation notes on the bibliography interface are available.
