// Amazon Jeffco 1.2.7 Library Lookup
// Sean LeBlanc
// Modified Josh Staiger's (excellent) code
// to adapt to Jeffco-Prospector search.
// TODO: Add in "other editions" search?
// TODO: General clean-up of unused code.
// Currently, this script will search for the book in the Colorado Jefferson County library.
// If not found there, it will search on Prospector, then Worldcat.
// Also inserts a search link on CD, DVD, and VHS items.
// Based on Josh Staiger's Wake County Library Lookup.

// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/

// @description While viewing a book on Amazon, this script will search for the book in the Colorado Jefferson County library. If not found there, it will search on Prospector. If not found there, it will try to search Worldcat. Also, it will try to detect when viewing an item that is a CD, DVD or VHS, and insert a search link into JeffCo Library to use on that page. Based on Josh Staiger's Wake County Library Lookup.
// @include http://*.amazon.*
// @include http://amazon.*
// @version 1.2.7
// ==/UserScript==
// CHANGELOG:
// 1.2 - Added check for VHS. Uses contains() to match partial path of image, as does the DVD check. Added slog().
// 1.2.4 - Updated due to Amazon changes.
// 1.2.5 - Altered DVD/VHS detection.
// 1.2.6 - Changed getTitleLocation() because of Amazon changes.
// 1.2.7 - Fixed getTitleLocation() again because of Amazon changes.
