Comment to: Improving the presentation of library data using FRBR and Linked data by Anne-Lena Westrum, Asgeir Rekkavik and Kim Tallerås. Code4Lib Journal, Issue 16, 2012-02-03
This is a very interesting article for anyone interested in how the public works with library catalogs. One additional aspect that would be especially interesting would be a comparison among patrons for the result sets as foreseen by FRBR, and those available through modern indexing practices. These can be seen in Worldcat now.
To take your example of Hamsun's Sult the uniform title is: Hamsun, Knut, 1859-1952. Sult, and searching this in Worldcat correctly http://www.worldcat.org/search?q=ti%3A%22sult%22+au%3A%22hamsun%2C+knut%22 gives 156 results that the patron can modify by format, other authors, dates, languages, and so on. This list can also be sorted by author, title, date, etc. Other indexes could be created too.
To get this kind of result, of course needs the catalogers to add consistently and correctly the uniform titles. But that is part of their job.
