All materials catalogued to the same level.
There is no marker or identifying factor within records to identify the three types of records. It is therefore not possible to use the automated system to generate separate samples of each record type.
The full classmark is recorded on the verso of the title page. The spine of the item carries the shelf mark - this has a maximum length so can be shorter than the full classmark.
