[Koha] Using Koha for small hybrid resource centre

I have been considering using Koha to catalogue and circulate a small (but growing!) collection of books, journals, e-books, article citations, company reports, web sites, online reports currently scattered across our intranet, WebCT, e-book services and an MS Access database. Before I commit myself to a far bit of work over the summer, I'd be interested in having a look at a system that is using Koha for a collection that is not predominantly print-based and makes use of the 856 field in MARC. Any offers? Thanks, Catherine Kennedy
