This article deals with the oeuvre of Abū Mansūr al-Tha'ālibī, a prominent literary figure of the Eastern part of the Islamic world in the 4th/10th century. It deals with some of the literary and social issues that led to the numerous problems of false attribution and duplication in his bibliography, such as patronage and the periodical reworking of his books. This is followed by an up-to-date bibliography for al-Tha'ālibī, based on archives, primary sources and secondary literature. Works in print and manuscript form are assessed as to their authenticity and content, including bibliographical information on published works and locations of manuscripts. A further list reunites lost works and those surviving in quotations with references to the extant passages.
