Thanks to Steven Cohen and Michael Fagan and Andrea Mercado [and me, and Michael and Andrew whose emails with similar code I didn't get til this morning], the WorldCat Lucky Bookmark lives! While I agree with Sarah that we can't expect our patrons to grok the bookmarklet thing, as much as we might like them to, this one is [nominally] for staff. Go nuts team!
