PUBLIC MARKS from decembre with tags exemple & information

Determines if an Amazon, Barnes and Noble, Powell's, or Netflix item (book, CD, or DVD) is among the holdings of the Atlanta-Fulton County Georgia Library System. When the user navigates to an item, the user script locates, if present, the ISBN-13, the ISBN-10, the title, the author(s), the actor(s), and the director(s) on the page. It then searches the library by ISBN-13 and ISBN-10, by title and each author, by title and each actor, and by title and each director. If a search returns at least one result, a "smile" icon appears above the product image. If the user clicks on the "smile" icon, the browser navigates to the library search result(s) for the item. If no search returns any result, a "frown" icon appears above the product image.
