The so-called Auctarium Garstense, compiled at Admont Abbey in 1181, used them as a source for its early entries.
These Excerpta Aventini cover the period from 748 to 939 and sometimes contain information found nowhere else, but since Aventinus sometimes altered the wording their reliability is suspect.
