A new york centric way to look at books.
You should save this text as bookborough.user.js
You probably don't want to use this and bookburro.user.js at the same time.
I've left in the reference codes of the original devs - give them
dough so they give us some new versions of book burro.
Any improvements/new versions of this will be found at
http://snarkhunt.blogspot.com
email me any suggestions, just use my blogspot @ google's email.
All I've added is the new york public library, brookly public library and the strand'
Fixed amazon, buy.com, removed the SE urls, as they aren't so relevant to NYC.

0.15 - Added BiggerBooks.com, Bookbyte, Booksamillion.com and eCampus.com
* 2005-10-02 *
0.14 - Made the bookburro window draggable

* 2005-09-19 *
0.13 - GreaseMonkey 0.6 compatibility fix to get working onclick handlers
- Added AJAX fetching from Powell's Books, figuring they want customers

/ Johan Sundström, oyasumi+bookburro@gmail.com
* 2005-06-24 *
0.12x - Added support for alldirect.com
* 2005-06-21 *
0.12r - works when injected before the page has finished loading; fixed price-parsing on Powells.com; removed Powells from list in the Burro box
0.11r - modified by Reify to work in Internet Explorer with Turnabout:
- The price wouldn't render on Amazon for some reason, so we now render with DIVs + SPANs
- Set style in a way that works in IE (element.setAttribute("style", str) doesn't work in IE)
- Moved data: URIs to one place to make the script easier to read
- Show/hide the price table rather than changing the box's dimensions to make code easier to maintain (don't have dimensions scattered throughout)
- Anchored top right icons to the top right instead of top left so their position will update automatically if the box has to be wider
- Branch to use MS or Mozilla XML parser
* 2005-04-25 *
0.11 - improved skin & add link to message if no results
0.10 - bug fix - don't show iframes!
0.09 - bug fix - alert were out of scope, plus a couple visual tweaks
0.08 - bug - use (function(){ code })(); so you don't kill other javascript
0.07 - use AWS to grab amazon's prices
* 2005-04-24 *
0.06 - wasn't checking for ISBN= in the url as well!
0.05 - added Amazon marketplace
0.04 - worked on skin to make it PURTY
0.03 - use AJAX to add the prices
0.02 - Improved interface
0.01 - initial releasea
