get notified when what you're searching for is at the library

InvisibleHand is a handy extension for Chrome, Firefox, Safari, and IE that unobtrusively notifies the user when the item they are searching for to buy is available for a lower cost on another website.  The notification also gives a link to the relevant product page on the competing retailer's website.

I really enjoy the extension, as do others, but the only thing better than notifications of cheap items would be notifications of FREE items available to you.

How about an extension that notifies the user when what they are searching for is available at their local public library??

Many people who don't want to pay for movie rentals, for example, may check out movies from their local library.  Generally, they would need to browse the shelves at the library or look at the library's online catalog.

The website worldcat.org helps people find items in libraries near them; why not develop a worldcat browser extension that notifies people when what they are searching for is available at their local library?

Know anyone who wants to work on this?

Big waves in the forecast for the Great Lakes

If you've ever wanted to see people surfing on the Great Lakes, this weekend will be a great time to do it.   Lake Michigan should see waves in the 10-foot range and Lake Superior will have some 15-footers.  And while Sheboygan, WI isn't positioned to see the biggest waves, it will be hosting the Dairyland Surf Classic 2010 this weekend.  My guess is that many of the best Great Lakes surfers will be drawn to places with bigger waves, but the event should be fun to attend nevertheless.
