I’ve posted an improved version of the amazon2melvyl script, which automagically adds Melvyl (UC Libraries Catalog) lookup links to linked Amazon items. This new version takes advantage of Greasemonkey’s new XMLHTTPRequest support to look up related ISBNs via OCLC’s xISBN web service, vastly increasing the chance of a successful lookup. It also uses in-line data: URIs for the icons, saving my bandwidth and your privacy (not that there was any snooping going on, but still). Thanks to Jeremy Dunck and Phil Ringnalda for these great suggestions. You can get the new version here.
