Dallas Public Library’s use of the NY Times Best Sellers API (application programming interface)
The NYTimes First Look Blog asks: Have you visited a library Web site lately? Maybe you think you have no reason to, especially if you’re not a regular patron of your local library. But on most library sites, you can do much more than look for a book: public branches offer everything from digital photo archives to podcasts to holiday cards. With so many services available, you might even forget to search the catalog.
Here's the Dallas Public Library's homepage, featuring the bestseller list.
