LibraryLookup uses Creative Commons license
When somebody wrote yesterday asking whether the LibraryLookup code (such as it is!) was licensed for public-domain use, I realized this was the perfect opportunity to try out the Creative Commons licensing procedure. It couldn't have been any simpler -- it took all of about 10 minutes. I chose the Attribution-ShareAlike license:
Attribution. The licensor permits others to copy, distribute, display, and perform the work. In return, licensees must give the original author credit.
Share Alike. The licensor permits others to distribute derivative works under a license identical to the one that governs the licensor's work.
Embedded in the HTML generated by the Creative Commons website is this slug of RDF:

Method for using a JavaScript bookmarklet to extract the
ISBN from an ISBN-bearing URL and use it to look up the book elsewhere,
particularly in a local library. Related development: directories of online
lookup services offered by many libraries.

Since the whole point of this exercise was to create a meme that would propagate widely, I considered the public domain dedication. Who, after all, would try to patent something as simple and obvious as a regular expression used in a JavaScript bookmarklet to capture an ISBN and make a referral to a library? But stranger things have happened. I hope this license will accomplish two things. First, encourage linkage back to the LibraryLookup project so I can keep track of how this evolves. Second, discourage any effort to patent the idea.
