Archival sources for Du Cange's Latin Glossarium?

Question

Tried this in the languages forum and got nothing as it is admittedly obscure. I am trying to figure out what the references in the entries in Du Cange's Glossarium correspond to. For instance, after a definition, I see "Lit. remiss. ann. 1352, in Reg. 81. Chartoph reg. ch. 507:" from which follows a passage in which the word I am looking up is used. I get that it comes from a register from 1352, but I can't find a legend that will point me to the source of the quote. If anyone could tell me what to do or where to find more information either in Du Cange or in some other book or article I would greatly appreciate it.

Answer 1

Apparently this is a known problem - you are not the only one having trouble finding the sources. Read the last line below:

Du Cange’s original compilation (3 vols. Paris 1678) underwent various reworkings, eventually reaching 10 volumes (Niort 1883–87). Although it contains a huge amount of material and numerous indexes and is often cited, its sole principle of organization seems to be alphabetical, and sources of quotations are often very hard to trace and date.

Du Cange is best known for his glossary of medieval Latin (Glossarium ad scriptores mediae et infimae Latinitatis) in three folio volumes (1678)33 and a corresponding glossary of medieval Greek in two volumes. Like Tillemont, Du Cange habitually worked from twelve to sixteen hours a day, and for the Latin glossary alone he examined upwards of six thousand manuscripts besides printed sources. (from section 32 - 33, about 2/3 of the way down the page)

Many of these 6000 manuscripts are probably no longer in existence, and may be some of the sources he cited.
