Adding to the Thesaurus

The Thesaurus is a list of Subject Headings you choose from to assign to resources.

The list is basically moderated by SCIS (although over the years your list may have... ummmm... deviated a little from the true list, both from necessity and lack of understanding)

So, you can:-

Add Valid Subject Headings
Add Non-Valid Subject Headings (or See References) that refer a researcher from a dodgy term to a term deemed acceptable to the guardians of all that is stored and cataloguable...

A few things to note:

Base Control Numbers

When a new subject heading is adopted by SCIS it is called a Base heading
Other subjects can be formed using a Base heading by adding a "subdivision" (eg Base Heading - Australia)
If you are adding a Base heading then the defualt control number is ok (but it would be better to lookup the SCIS database and find out what the real base control number is (if your new subject does not already exist in the SCIS list then we don't encourage you to add it (unless you are running a specialist collection that SCIS is not really good for... schools should stick to SCIS as a validation list)
If you are adding a new subject heading that is a Subdivision of a Base heading then you should use the button to find the Base heading control number to use
This sounds like a whole lot of hoopla but when a round of political correctness changes are released by SCIS you'll be very glad you stuck to the rules! (Or you'll pretend you don't know SCIS wants you to adjust your database!)
