Lustrum: Internationale Forschungsberichte aus dem Bereich des klassischen Altertums (English: "International research reports in the field of classical antiquity")[1] is a refereed[2] review journal in the field of classical studies.

[6][7] In principle, these reports were supposed to come out every five years;[8] a lustrum was a five-year period of time in Ancient Rome.

[15][16] Some bibliographical articles can be quite lengthy and cover a much wider span of scholarship; an article by University of Thessaloniki professor Ioannis Touloumakos which covered scholarship on Aristotle's Politics during the period 1925–1985[17] is 700 pages long and took twelve years to be fully published.

Plans to create this new journal were first made during the August 1954 meeting of the International Congress of Classical Studies.

[18] The first volume was published in 1957 by Vandenhoeck & Ruprecht in Göttingen, Germany, and included three articles[23][26]—including one by Mette on Homeric scholarship.

[31] He retired after working there for twenty-five years due to his age, and Marcus Deufert [de] became his successor at Lustrum.

[19] Lustrum is also mentioned as a resource in various guides to reference materials for classics[18][45] and related fields;[46] Fred W. Jenkins described the series in his 2006 book as "quite useful for keeping abreast of the literature on a wide range of authors and topics".
