Published yearly since 1930, the "International Bibliography of Historical Sciences" (IBOHS) is an international bibliography of the most important historical monographs and periodical articles. Volume 67 contains 8,701 entries from the period 1998. Listed in this bibliography are monographs and periodicals published throughout the world, which deal with history from the earliest to the most recent times. Included within the scope of the historical sciences is the field of international relations. The IBOHS is thus currently the only continuous bibliography of its kind covering such a broad subject period and geographical range. The IBOHS is compiled according to stringent academic standards, it keeps scholars and academic organisations informed of yearly developments in the field of historical studies. The systematic and chronological arrangement was developed by the Bibliographic Commission of the International Committee of Historical Sciences. The new edition of the IBOHS has retained this familiar tried and tested format. The works are arranged systematically according period, region or historical discipline, and alphabetically according to authors names or, in the case of anonymous works, by the characteristic main title word. The newest bibliographies and source material are emphasised and the bibliographies contain a geographical index and an index of persons.
