1. Added entries for titles in the context of a machine-readable catalog

1. Added entries for titles in the context of a machine-readable catalog. The guidelines for providing added entries, including those for titles, are embodied in the cataloging rules (AACR2), the LCRIs, and any administrative decisions made locally by a particular library. These guidelines reflect the conditions under which the bibliographic infrastructure formally calls for "added" access. In a unit-card environment, such access required preparation and filing of an additional unit card for each "added" access (as well, of course, as added access that was "derived," e.g., from the title).

Within the machine-readable environment, the MARC format content designation conventions support the formal guidelines mentioned above. What is different about the machine-readable environment, however, is that "access" becomes a function of the particular system used in support of the machine-readable catalog, and that in turn reflects the decisions of the system designers. There is, then, embedded within a machine-readable bibliographic record, not only the access called for by AACR2, as reflected in the content designation, but also the access designed into the system. For example, AACR2 may suggest no title added entry is needed in a specific situation. The mechanism used in this case is indicator position 1 of the 245 field containing the value "0" (No title added entry). However, a particular system may have been designed to index all 245 fields in all cases. Thus title access is provided in spite of the setting of the indicator value otherwise. Nevertheless, the guidelines in this LCRI on title added entries reflect and amplify those called for in AACR2 only; they do not take into account the kinds of access that any one system may (or may not) provide.

2. Controlled/uncontrolled. Added entries may be "controlled" or "uncontrolled." "Controlled" means that the data constituting the added entry are in the form that has been determined to be used in formally referring to an entity according to AACR2 and LCRIs. It is the "established" or "catalog-entry" form for the "name" of an entity, including a work. When it is determined that an entity is primarily responsible for the creation/emanation of a work, the controlled form for an entry for the work is a name/title combination. Otherwise, it is the title itself in the form that is determined to be used in the catalog ("uniform title heading"). Controlled added entries for works are stated in MARC in fields 700 , 710 - 711 (name/title combinations) and 730 (uniform title heading).

The found form of a title, a form appearing on an item and limited to the title itself, divorced from any entity that may be primarily responsible for the work, is an "uncontrolled" form. It has not gone through the formal process of being established (catalog-entry form undetermined, although in some cases the controlled and uncontrolled forms might turn out to be one and the same). The focus of this LCRI is on providing added entries for titles in an uncontrolled form ("title added entry"). The LCRI states the various guidelines relating to title added entries. It begins with a description of the data constituting them and the mechanics of stating them in a machine-readable bibliographic record. These aspects are described first so that the examples used in subsequent sections of the LCRI will be understandable. Next is the basic guideline for title added entries for titles proper followed by guidelines related to permutations of titles proper. A section on items without collective title is followed by one on the guidelines related to other titles borne by an item. The LCRI concludes with sections on title changes related to monographs, integrating resources, and some electronic serials.
