Primo demo at Vanderbilt
Marshall Breeding points out their test implementation of Ex Libris‘s new catalogue application, Primo: code-named Alphasearch, it is “the first time that a live Primo implementation has been made available to the general public.”
It does some manifestation grouping. Here are some search results for The Three Musketeers. Notice the link “11 versions in 3 languages published between 1893-1976.”
I find the interface awkward, especially its insistence on doing everything as a search, so I’ll leave further exploration up to you.
