NASIG Newsletter
I stumbled across this just a couple of days ago, though it’s from September: Does FRBR Include Serials? A FRBR Implementation for All Formats (scroll down to the middle), by Craig Thomas, a report on the spring 2005 meeting of the New England Technical Services Librarians, filed in the NASIG Newsletter (September 2005). John Espley from VTLS gave a demonstration of Virtua.
Of the design considerations addressed, it was likely the question of display that aroused the greatest interest, many attendees curious as to what FRBR records even look like. Espley demonstrated VTLS’s proposed solution to this design challenge using as an example Beethoven’s Symphony No. 6. (Today’s demo was PowerPoint-based, rather than live). On the top half of the screen, Virtua’s split screen interface displays the work-expression-manifestation relationships within a family of records as an expandable tree structure indented according to the entity level. Distinctive icons denoting each level provide added clarity. On the bottom half of the screen appears the record corresponding to the point in the tree one is highlighting. Each record below the work level possesses both a control number (field 001) and an 004 linking field (appropriated from MARC 21 Holdings Field 004, Control Number for Related Bibliographic Record). The latter corresponds to the control number (001) of the record at the preceding level. Manifestations thus link to their respective expressions; expressions link to the work.
