Subject Indexing ToolsSubject Indexing Tools
There are two main INIS products used for indexing: WinFibre and CAI•WinFibre – for input preparation both bibliographic and subject indexing•CAI (Computer Assisted Indexing) – for subject classification and indexing
INIS/ETDE Thesaurus and INIS Subject Category Codes are incorporated in both.

“Hidden terms” are character patterns representing the different appearances of a concept in the free text, which is indexed by one or more descriptors. • handled similar to “forbidden terms” with one or more USE
relations• CAI internal only • not exported to INIS production system• not exported to FIBRE • not printed in any appearance of the thesaurus • support identification of descriptors in the free text
