The Casaubon-Kaibel reference converter is a tool for finding concordances between the numerations used in the two editions of the 15 books of the Deipnosophists of Athenaeus of Naucratis by Isaac Casaubon and Georg Kaibel.
By inserting at least one of the two references (by Casaubon or by Kaibel), you get the corresponding reference with links to the relevant pages in the two editions.
Casaubon reference system – Isaac Casaubon (1597)
After the reference to the book number, this system includes an arabic numeral referring to the page of the edition of Casaubon followed by a letter (a-f) corresponding to the subdivision of the page into sections of about ten lines of text (e.g., 12.530d).
Kaibel reference system – Georg Kaibel (1887-1890)
In this system each book is logically divided into paragraphs corresponding to units of sense and the paragraphs are referred to with arabic numerals whose numeration starts again at the beginning of each book (e.g., 12.40).
