Created in 2006, Cover Browser displays galleries of comic book (and book, pulp, games, DVD or magazine) covers for comic book fans like myself to explore & enjoy (there's also links to buy comics). At the moment, there are 150,618 covers from 2,059 different series available. Most of the covers and associated data have been assembled using the nice Yahoo Image API, eBay, the Google Web Search API, the Amazon API, the Yahoo Term Extraction API, different homemade crawlers, and manual sorting. I'm also working with collections you send in or homemade scans. You can read more on the technical background. Also see the Cover Browser Labs.
