Deutsche Nationalbibliographie und Bibliographie des im Ausland erschienenen deutschsprachigen Veröffentlichungen: Monographien und Periodika, Fünfjahres Verzeichnis. 1986-1990. Schlagwort- und Stichwortregister mit systematischer Übersicht der Schlagwörter. Reihe E.. Zweiter Teil

The Deutsche Nationalbibliographie (DNB) represents the comprehensive record of all German-language publications, a mission maintained by the German National Library in Leipzig and Frankfurt. The Fünfjahres-Verzeichnis, or five-year index, serves as a cumulative reference work that consolidates bibliographic data into manageable multi-year sets. This specific volume, covering the period from 1986 to 1990, was published in the late 20th century to provide researchers, librarians, and bibliophiles with a structured retrieval tool for the vast output of German literature during the final years of the Cold War era.

The design of this index follows the rigorous standards of German library science, prioritizing systematic categorization and precision in its subject indexing. By organizing the Schlagwort- und Stichwortregister—the keyword and subject index—the publication ensures that researchers can navigate complex bibliographic entries efficiently. The work is widely regarded in professional circles as an essential reference tool, prized more for its functional utility and archival integrity than for artistic aesthetics or commercial appeal.
