UPIC: An ISBN Alternative
Just wanted to plug a new service I'm offering to publishers and customers of publishers: the Unique Publication Identity Code, or UPIC, a free alternative to ISBNs for small to medium-sized publishers.
Go to http://upic.taur.net and enter the UPIC from a book, magazine or whatever, and you'll get much of the standard ISBN data: Publisher info, first publishing date, status (in-print or not), et cetera. Fanzine publishers, comic book printers, makers of art portfolios, and anyone else who offers printed goods for sale is invited to use this service.
The service is free to publishers and users, but contributions are of course welcome. The features of the site are still somewhat in flux, but the current version is up and working.
Check it out!
