- Abstract
- Reports results of a study, conducted at Rhode Island University Library, to determine whether cataloguing records known to be missing from a library consortium OPAC database could be identified using the database search features. Attempts to create lists of bibliographic records held by other libraries in the consortium using Boolean searching features failed due to search feature limitations. Samples of search logic were created, collections of records based on this logic were assembled manually and then compared with card catalogue of the single library. Results suggest that use of the Boolean OR operator to conduct the broadest possible search could find 56.000 of the library's missing records that were held by other libraries. Use of the Boolean AND operator to conduct the narrowest search found 85.000 missing records. A specific library search made of the records of the most likely consortium library to have overlaid the single library's holdings found that 80.000 of the single library's missing records were held by a specific library
