If you are ever looking to get a whole mess of ISBNs into Delicious Library (say, for example, from a different book database), and have DL2 freshly slurp all the books’ info from the web, you should use this Applescript. It saved me Lotsa Workâ˘.
(I tend to prefer Bruji Software’s Bookpedia over Delicious Library from a straight-up features standpoint, but I do use both)
