NLB xISBN bookmarklet
There's now an official OCLC xISBN bookmarklet for the National Library Board, Singapore! You can install it here. Basically, Eric Childress of the OCLC noticed my blogpost about modifying my NLB LibraryLookup bookmarklet to take advantage of the xISBN functionality, which lets you search for various editions of a book, which have different ISBNs, with a single ISBN search. That is to say, my post was about my inability to modify the bookmarklet. Jeff Young, also of the OCLC, then created a bookmarklet specially for the NLB catalogue and e-mailed me about it. Thanks, guys.
