Finlay Thompson + Katipo are currently developing on-line request feature for Koha. As this is a work in progress (no published ETA?) and we have an immediate need for this at one of our schools, we have hacked up a quick demo. What we have done may be of interest: http://www.saas.nsw.edu.au/wiki/index.php?page=OnLineRequests All feedback, comments are welcome :) R.
