Candidate terms (terminology suggestions) are submitted to FISH all year round. Terms are processed and usually added to the FISH thesauri and authority files as and when they come in. Every year the thesauri are updated and uploaded to this website, here you can download the thesauri in CSV and PDF formats and at Heritage Data, a related website, you can access the terminologies in LOD format.

Due to ongoing technical issues we have been unable to produce updated .pdf versions of the thesauri for this release but they all remain current except for those that have been updated since February 2021; the seven affected thesauri are:

Archaeological Objects, Components, Event Type, Historic Aircraft, Monument Type, Object Materials and Resource Description (Thred).

Please accept our apologies for any inconvenience that this may cause; Click here to view a list of terms added and changes made to version 26 of the aforementioned thesauri.
