This site is currently in the final phase of being upgraded. Not everything may work as intended and in the interim, we are unable to offer you the previous, stable version of the website since we lack the storage capacity to keep both versions running on the server. It should not take long, however, before the final hurdles are overcome.

A module for identifying agents - encompassing persons, peoples and organisations - and managing information about them has been around for many years, continually evolving as time went by, but what was absent all this time is a public interface for accessing relevant data in a user-friendly way.

This is a first attempt at offering such an interface, which is provided "as-is" and should be considered beta-quality for now (not that there is any official product release cycle as such but using the label is a convenient means to sound the right alarm bells). It currently consists of a basic search, aggregated data overviews for individual agents, and hover-card labels that you will meet elsewhere in the catalogue.

I am aware of duplicates, uneven coverage and other shortcomings that typically arise from the progressive nature of this website or simply, lack of personpower. An earlier version of the interface was available to editors partly because it helps us address some of those issues. None of these objections, however, seemed to weigh heavily against the alternative, which is having nothing at all to offer.

Note that for convenience's sake, many agents are not formally indexed but are nonetheless included by exclusive virtue of being linked. It is a wonderful forte of the system that allows us to retrieve and bring together disparate data from disparate data sources, but some useful metadata will be missing and discoverability is more limited as a result. For instance, we may be linking to a scribe whose name and associated data can be retrieved and presented, but without, say, a floruit it will be difficult to find this person within the appropriate time range. I say "difficult" because it is possible, to an extent, to rely on the dates we have, if any, for associated objects (manuscripts, scribal hands), but such a circuitous approach comes with limitations of its own and is not necessarily methodologically sound.

Meanwhile, I hope that the new interface will improve your experience in using this website. Next up are thematic categories for scribes (in the broadest, non-pejorative sense of the word), authors and scholars.
