The quality of an STCV description depends heavily on the correct application of the cataloguing rules. The process followed by STCV relies on two main principles that help eliminate as many mistakes as possible.
An STCV description is always made 'with the book in hand'. Descriptions are never added from other databases, catalogues or reference works. Even when adding additional copies (doubles) to existing descriptions, the entire copy is checked 'in hand'. Information from additional copies may be used to improve the original description, for instance when the original autopsy was based on an incomplete copy.
Each new record is thoroughly checked by at least two people.
*A first STCV cataloguer creates a new description following the STCV cataloguing rules ('''Step A: Description''').
In the online catalogue, users can see whether a description has completed the ABC-process or not.
*Records that have not yet been verified and corrected, have a status of '''Preliminary''' (code <code>sa</code>). These records may still be incomplete or contain some errors.
*After verification and correction, the status will read '''Verified''' (code <code>sc</code>). These records may be relied upon.
A number of additions and changes were made to the cataloguing rules in October 2015. Records created before this time were marked with the 'status' ['lidmaatschap'] (code <code>so</code>) ('''STCV - old model'''). When editing such a record, cataloguers are required to check the book, make the necessary changes and then, once done, delete this 'so'-membership. If none apply, please also delete the 'so'-state. This way, we can keep track of the status of each record. Eventually, all records will be updated to adhere to the latest cataloguing rules and the state of 'so' will be redundant and eliminated.
