As part of OEM-UK we will be creating MARC records from metadata entered in Drupal, we would like to be able to adopt an accepted standard for rating the level of ‘cataloguing’ of these records. There are two main standards for defining the level of cataloguing;
1. AACR2 (1.0D) defines 3 levels of cataloguing, first level, second level, and third level. The first level is the lowest threshold and third level is full AACR2 (practically impossible)
a. Abbreviated-level cataloguing (does not meet AACR2 first level standards)
b. Minimal-level (same as AACR2 first level)
c. Core-Level (between first level and second level)
d. Full-level (same as second level)
OEM-UK decided to use the OCLC criteria to rate our records.
OEM-UK material rated in terms of OCLC levels of cataloguing
1. Textbooks will attain the abbreviated level of cataloguing
2. Exam papers will not attain any OCLC level of cataloguing
Reasons for level of OEM-UK material
1. All OEM-UK material miss the first 2 levels (‘Full’ and ‘Core’) for multiple reasons e.g. they require that the fixed fields are coded in full (whether an index or illustrations are in the work etc.). We do not record this
2. The textbook records will not contain the dimensions of the work so can’t be rated ‘Minimal’ (this is the only information for this level that we lack in the textbook records)
3. The exam records fail to meet the lowest level (‘Abbreviated’) for 2 reasons; we have not recorded the publisher or the pagination and the also fail to meet Minimal level as we have not recorded the physical dimensions
Conclusions – ‘just in case metadata’ v the semantics
At OEM-UK if we can’t automate its creation we discard ‘just in case metadata’, instead concentrating our resources on semantic enrichment. Subject indexing is only mandatory in the top 2 OCLC levels of cataloguing (Core and Full); but all of the OEM-UK material is indexed.
Dropping exam paper publishers and pagination, and the physical dimensions of the books and therefore missing out on higher OCLC’s levels of cataloguing in order to free resources to enable us to semantically enrich every record with subject indexing is, we believe, a price well worth paying.
