Hello, I'm grappling with something exciting at the moment but would like some help from the Koha community. I have a brand new Google Android phone, which has on it an app called Barcode Scanner. It works by using the phone's camera as a barcode reader to scan an item's ISBN then search something like Amazon or Google Books to find a match (which you can obviously use to purchase the item). Think of seeing a good book your friend has, scanning the barcode and ordering a copy for yourself. Where Koha comes in is that it offers one the ability to enter a 'custom search' URL. So I started to think: what if I set this to be my library's OPAC and did an ISBN search of Koha? That would give me the ability to search my Koha using a smartphone barcode scanner. The problem is, I can't get any results returned. I've set the 'custom search' URL to be http://<library server>/cgi-bin/koha/opac-search.pl?q=%s (where %s is the ISBN returned by the barcode scanner.) The problem is that I can't get any results returned. The ISBN I'm using to test it is 9780143018674 but the page I end up on is 'No result found! No results match your search for 9780143018674.' Is there a special URL I should use to complete an ISBN search? Can anyone help me? Mark Osborne
