The lists may be scanned occasionally. NACO records may be created. AUPFor the AUP cash loans, we check the "general to specific" changes. These are changes to an authority record which make it more specific, meaning cash loans some of the bibliographic records that previously matched may no longer do so. For example, when a date is added to a personal name heading, payday advance the name without the date may represent two or more different people.

LTI usually does not change the bibliographic records because of the risk of inappropriate changes. See Appendix 2 for detailed instructions for staff doing this work. Non-filing indicators (both AEX and AUP)As of the fall of 2007, we use LTI's non-filing indicator fix.

Refer any problematic non-filing indicators to Amy Turner. With LTI customers reporting problems, the fix is continually refined. Authority records in the catalog In DRA, our authority file was a subset of the LCAF supplied by LTI.

In Aleph, it is theoretically the entire LCAF. As part of Aleph implementation, the LCAF to date was loaded. The project of setting up ongoing updates is on indefinite hold, because Endeca does not display or make direct use of authority records, and the Classic catalog is being phased out. Thus the focus of our authority control effort is consistency in headings, rather than cross references. LTI has demonstrated that they are very open to suggestions for improving their processes.

When national standards do not allow certain references, we can suggest them to LTI as proprietary references, thus improving their link rate. LTI is also open to suggestions that certain references be "blocked. For example, the reference from "Education series" to "Occasional paper. Education series" converts several different "Education series". We can also suggest proprietary authority records. For example, LC policy does not allow creation of AR's for the main entries of unanalyzed serials, but we may want an authority record to prevent mislinking of 130 fields which are very similar to other authorizedSuggestions to LTI should be sent to Amy Turner, who will forward them to Marsha Hunt, our contact.

There had been increasing problems with the complex logic based on item processing status, and using the CID field as a trigger would simplify the extract considerably.
