Hi We recently implemented a new third party web catalogue (Aquabrowser). So far so good, and separating the web based discovery layer from the monolithic ILS seems to be the right direction. However there seems to be two areas of weakness: Holdings and 'My Accout' (renewal, reservations). i.e. the need for *any* catalogue/discovery system to allow users to see holdings and account info from *any* ils. I'm trying to get my facts right on the current situation. Any help appreciated. re Holdings. Two things come up when asking around and looking on the web (some what briefly), Z39.50 and ISO 20775. Can anyone give me an idea if any/many/all (ILS) Z implementations have implemented the holdings information? Is there a way of testing this using a client such as yaz (e.g. a worked example of seeing holdings via Z) Is there interest from ILS suppliers in the ISO holdings standard, are any of them implementing it? http://www.loc.gov/standards/iso20775/ http://www.portia.dk/zholdings/ http://www.nlbconference.com/ilds/plenary4B.htm Thanks for any info Chris -- Chris Keene [log in to unmask] Technical Development Manager Tel (01273) 877950 University of Sussex Library http://www.sussex.ac.uk/library/
