Does your library have too many choices on the OPAC’s advanced search page? From the point of view of our librarians we don’t, but I think from the point of view of the patrons we do. 43 choices? And many of those categories encompass the same materials or genres. You could easily group our categories using format, audience, or other criteria:
- DVDs: DVD, DVDJ, DVJN, DVDN
- Videos: AV, AVJ, AVJN, AVNF
- Movies: DVD, DVDJ, DVJN, DVDN, AV, AVJ, AVJN, AVNF
- Books for adults: AF, MYS, SCI, WES, LP, LPNF, PB, BIO, NF
- Large Print: LP, LPNF
It’d be great if you could define “category groups” in Koha to allow patrons to easily search multiple categories at once. Until that comes about, how can we approach the problem from the front end?
Here’s a little experiment I worked up. This is just a static example page to demonstrate the selections. Some parts of the OPAC omitted for simplicity.
Try clicking the links at the top of the category table. Clicking “Books” will select all collection codes which I’ve defined as a book for adults. Clicking “Audio Books” will select any category which could be defined as an audio book, whether it be on CD, cassette, or Playaway.
var books = "#ccode-1,#ccode-5,#ccode-12,#ccode-13,#ccode-14,#ccode-15,#ccode-16,#ccode-17,#ccode-18,#ccode-19,#ccode-27"; var movies = "#ccode-2,#ccode-3,#ccode-4,#ccode-6,#ccode-23,#ccode-39,#ccode-40,#ccode-41"; var lp = "#ccode-13,#ccode-14";
Defining your “supercategories” could be as difficult as defining your original categories in Koha. What criteria do you use? Audience? Format? Content? In my example I mix all three. Would that be confusing to patrons? I may yet add this to our OPAC, but I’ll have to ponder these issues a little more.
