Karlsruhe, Badische Landesbibliothek, Kat. 11
Selected Canon Law Collections, ca. 500–1234
"Karlsruhe, Badische Landesbibliothek, Kat. 11" is an erroneous reference. "Kat. 11" presumably refers to volume 11 of the Karlsruhe catalogue Die Handschriften von Lichtenthal (1987) which contains no description of a Gratian copy, but one of an abbreviation of Gratian: Karlsruhe, Badische Landesbibliothek, Kl. L. 102.
