[Koha] integrate Z3950 search in OPAC

We are interested in integrating the Z3950 search found within Catalogue module into OPAC, so that a patron can not only search against KOHA itself but also search against other Ztargets. On the search result pages, hits found from Koha plus hits from other sources can be displayed together with source Ids/names. Could somebody share some ideas? Are there any existing examples and/or showcases? Thanks Sun --------------------------------- Make free worldwide PC-to-PC calls. Try the new Yahoo! Canada Messenger with Voice
