To be able to discriminate between several thesauri of the same type, e.g. between different subject headings thesauri, we use the field 0501 / 002A,subfield $a / $a with the value used in subfield $2 of the related bibliographic field. In this way, there is always room for thesauri, without adapting field 0500 / 002@.


The so-called MATADI is a single capital letter that can be used to limit a search to a certain type of resource, like authority records of personal names, corporate bodies, topical terms, etc. The MATADI code for authority records is equal to the second position of tag 0500 / 002@.
