The list for volume XXIV covers works published and dissertations completed in 1990 and additional listings for 1988 and 1989 which did not appear in volume XXIII. The purpose of the list is to provide an overview of scholarship in the field of Austrian and Habsburg history. We do not pretend to provide an exhaustive bibliography for scholars doing research on specific topics. We exclude coffee table books, monographs of less than 100 pages, exhibition catalogs, articles under ten pages, and book reviews unless they have clear scholarly merit. Consistent with the scope of the Yearbook, the list includes scholarship on successor states other than Austria if it has a clear thematic link to the Habsburg Monarchy or the Republic of Austria. The entries fall within several broad chronological periods. Rather than offering a thematic presentation within them, we provide a subject index, which is keyed to the numbered entries, at the end. Entries are numbered consecutively throughout, which permits cross-referencing works in more than one period and under more than one subject heading. We place the title of an edited work in the earliest period for which it contains contributions, and cross-reference where applicable in other sections. We list the individual contributions in collected works in the special section entitled "Collections and Conferences." We compile the list using the computerized databases LC-MARC (Library of Congress), Historical Abstracts, Dissertation Abstracts, MLA Bibliography, Philosophers' Index, Religion Index, and other indexes which are part of the DIALOG on-line data service. In addition, Dr. Peter Urbanitsch contributes entries from German and other western language journals and books that are not in the DIALOG system, as well as dissertations completed at Austrian universities. For non-Western-language works, we have indicated (but not translated exactly) the title's meaning in brackets and identified the original language. We have used commonly accepted English-language names for cities of publication (e.g. Vienna, not Wien; Cologne, not Koln; and Prague, not Praha).
