Hello all, I'm not involved with any library (other than as a patron of my local county system), just lurking on the Koha list because I think it's a cool project. I was hoping that people who are involved with running koha in real library settings could comment on the perceived pros and cons of a "review and suggestions" enhancement to the koha database, a'la amazon.com. I have found myself increasingly using amazon.com as a source of feedback about books in a variety of situations; both when I'm considering a book to buy, or when I'm looking through our community library collection and wondering what books to check out. Having the reviews available is good, but I find the "people who liked this book also liked XYZ" to be really addictive. I can follow chains of related books this way, reading reviews as I go, and find some interesting things that I never would have come to on my own. I realize that there is a fairly large critical mass of reviews that must be present in a system before this really works, and I've been thinking about various ways one could share review collections between libraries. Before I get too into db schemas and appropriate SQL queries, are there some downsides to having this in the system that people anticipate? Or different review'ish schemes that seem more helpful? thanks, -emile
