I've just tried isbn-to-bibtex with the isbn entry "0201500647" (Feynman lectures on physics). It fails with:
--8<---------------cut here---------------start------------->8--- funcall-interactively: Wrong type argument: stringp, [((url . ["http://www.worldcat.org/oclc/67451431?referer=xid";]) (publisher . "Addison-Wesley") (form . ["BA"]) (lccn . ["89000433"]) (lang . "eng") (city . "Reading, Mass.") (author . "Feynman, Leighton, Sands.") (ed . "8th print.") (year . "1996") (isbn . ["0201500647"]) ...)] --8<---------------cut here---------------end--------------->8--- However, isbn-to-bibtex-lead gets me to the right page with a bibtex entry ready to be copied. Julien.
