Access points are a very important part of the catalog record. These provide the retrieval points for those using the catalog.
Access points are searchable fields.
These are the fields that require authority control. This means that you must use an established form. As long as authorized headings are used, all the books on one subject, or by a particular author, or in a series, should be in the same place in the online catalog or card catalog. In most systems the standardized numbers are also access points. The order of the personal names and the way the names are displayed on the title page or chief source of information is important.
