The ''Ṭabaqāt al-ʼUmam'' has been transcribed and translated into many different languages in many periods and cultures. The original document is not extant and discrepancies in the translations creates problems for historians, including variations in the title of the book.
Discrepancies in the content of the editions appear with some versions omitting words, sentences, paragraphs or entire sections. Some omissions or variations may have arisen through scribal error, or difficulties of direct translation, while others arose, perhaps deliberately, out of the political, religious, or nationalistic sensibilities of the translators.
