We have in our possession several handwritten registers, in the form of books all dated after 1755, from the old archives of the Brotherhood of St. Eloy, which are valuable sources for the study of this Brotherhood in the latter stages of it activity, i.e., from the end of the 18th century and the first half of the 19th century.

Among these volumes, we have found registers of accounts, inventories, correspondence, information about the inspectors and other relevant elements of historic interest.

Some of these registers, namely those of the 18th century, are well-worn and somewhat damaged.

 Requests for studying them are evaluated on a case-by-case basis.
