They have indexed some 3.7 million records from their library online catalogue and set up a faceted search and browse tool. <\/p>\n<p>What is faceted searching and browsing? Traditionally search environments like those for finding items in a library have you fill in fields. In Blacklight you can both search with words, but you can also add constraints by clicking on categories within the metadata. So, if I search for &#8220;gone with the wind&#8221; in Blacklight it shows that there are 158 results. On right it shows how those results are distributed over different categories. It shows me that 41 of these are &#8220;BOOK&#8221; in the category &#8220;format&#8221;. If I click on &#8220;BOOK&#8221; it then adds a constraint and updates the categories I can use further. Backlight makes good use of inline graphics (pie charts) so you can see at a glance what percentage of the remaining results are in what category type. <\/p>\n<p>This faceted browsing is a nice example of a rich-prospect view on data where you can see and navigate by a &#8220;prospect&#8221; of the whole. <\/p>\n<p>Blacklight came out of work on <a href=\"http:\/\/www.patacriticism.org\/collex\/2007\/04\/11\/spotlight-on-blacklight\/\">Collex<\/a>. It is built on <a href=\"http:\/\/wiki.apache.org\/solr\/Flare\">Flare<\/a> which harnesses <a href=\"http:\/\/lucene.apache.org\/solr\/\">Solr<\/a> through Ruby on Rails. As I understand it, Blacklight is also interesting as an open-source experimental alternative to very expensive faceted browsing tools that comes out of the Collex project. It is a &#8220;love letter to the Library&#8221; from a humanities computing project and its programmer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Blacklight is a neat project that Bethany Nowviskie pointed me to at the University of Virginia.
