I've added a search engine for ReligiousReading.com, using the great FreeFind search engine service. There are lots of search engine alternatives, but I've been using FreeFind for such a long time, and I really like the amount of control they give you over the way your site is searched. It's so nice to be able to request daily re-indexing of the site!
You'll find the search engine near the top of the right-hand column! There's not much to search yet... but over time, I hope there will be!
