Book Burro
For someone as addicted to reading as myself, this extension for Firefox is a fantastic tool. Book burro provides a semitransparent dialog when viewing an Amazon page displaying book details. Clicking on this dialog expands the dialog showing the content that you have chosen. For myself, this is most useful for checking my local library for a book before I drop my hard earned cash on a new(or used) book. Many major libraries are available as well as the option for searching WorldCat. Book burro also shows many online book retailers with the current price of the book. This makes price comparison shopping absolutely painless. Book burro is easily configured to limit the number of retailers searched and to input your local library. Go grab the extension and give it a try. Book Burro
