// @name Google Books - Peninsula Library System Lookup
// @namespace http://www.japaninyourpalm.com
// @description Display the availability of Google Books search result in the San Francisco Peninsula Library System and add hyperlinks to maps & hours on Peninsula Library results page
// @include http://books.google.com/books?vid*
// @include http://books.google.com/books?id*
// @include http://catalog.plsinfo.org/search/i?SEARCH*
// ==/UserScript==
// Version 1.7 - altered amazon isbn search pattern
// Version 1.6 - indicate if book is avail as on online book - Jan 2008
// Version 1.5 - Updates to find book title on google - December 2007
// Version 1.4 - updated ISBN finder again - now just seeks any amazon ink
// Version 1.3 - updated my ISBN finder on google's book page
// Version 1.2 - improved the book DUE reg expression & looser books.google url test
// Version 1.1 - tidy and remove GM_log statements
// Version 1.0 -
// Integrated into Google Print book search results to let you know if the book you're paging through is
// available at a San Francisco Peninsula library. The script puts a small yellow box in the corner of
// your Google Print book search. Box includes job title. The script also linkifies the library names,
// on the library lookup results page, to point to the library's streetmap, hours and phone.
// (this GM script acts on 2 completely seperate pages)
//
// Based on Junk Blocker's Peninsula Library System Amazon Lookup
// http://userscripts.org/scripts/show/1072
// which is based on...
// Library Lookup
// http://userscripts.org/scripts/source/886
//
// Note:
// Google Print has a "Find this book in a library" link, which I found often uses an ISBN number
// which doesn't match the book I'm looking at.
// The floating div approach used here is much nicer anyway in that it tells me immediately if the
// book is avalable locally.
//
// To Do:
// - add Santa Clara County library lookup to the same div
// - add web service xISBN to search on alternate ISBN #s, since libraries usually carry older
// hard cover versions of the more recent book/ISBN you find on google print.
