    Abstract
    The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

    Abstract
    Archival collections are usually considered to comprise primarily printed or written material. This paper discusses processing archival sound recording collections. Sound recordings can be archival. That is, they can be: (a) material gathered to accomplish some activity; and (b) material not created for public consumption. The concept of original order, of prime importance in archival work, is sometimes difficult to reconstruct. However, standard archival methods of arrangement can be followed. With sound recordings, the finding aid is usually the only tool for access to any part of a collection. Subject access to archival sound recordings tends to be through forms rather than topics. Cataloging archival sound recordings collections in many ways is similar to cataloging of textual archival collections.

    Abstract
    For a long time music librarians have grappled with the problem of cataloguing music scores along with physical recordings, including videorecordings of musical performances, in such a way as to collocate als physical forms in an intelligible order. The critical problems are, how to identify the properties of musical bibliographic entities and then how to control each property in the bibliographic universe and in each of the subsets of that universe, such as the library OPAC. Examines the concept of the 'musical work' as it has been decribed by bibliographers, cataloguers and scholars of bibliographic control. Concludes that there is ample evidence that equality exists among the representations of a musical work regardless of their physical formats. An understanding of the concept of the musical work should obviate the need to reconsider forms of access under current cataloguing practice and lead the way to the next generation of bibliographic control for musical works
