Hi! We have a similar collection to Paul's naval and marine archive, I think--we have over 34,000 titles in our Koha catalog and we are not a lending library (although some materials do circulate to staff). I was surprised to read your message, Paul, about your finding a search speed penalty with 3.18.x--we haven't experienced any degrade in search speed, and are now on 3.18.06. I'm sorry that I can't provide any technical details on this, though--our Koha catalog is hosted and supported by ByWater, so perhaps if you contacted them they could provide you some information on our installation?
The feature in 3.18.x that we're using the most (if I remember correctly about when it was included!) is the advanced item search--it's so handy! It's been very useful for us. The adaptations for RDA have also been very useful for us, but perhaps we find this more useful than others, since we contribute to OCLC and all our original cataloging is in RDA. Cheerio! --h2 ~~~~~~~~~~~~~~ Heather Hernandez Technical Services Librarian San Francisco Maritime National Historical Park Research Center 415-561-7032, heather_hernan...@nps.gov http://www.nps.gov/safr/learn/historyculture/museum-collections.htm "The sailor does not pray for wind, he learns to sail."--Gustaf Lindborg _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz https://lists.katipo.co.nz/mailman/listinfo/koha
