	Extending Koha	Extended Roman
	This chapter shows how you can add various enhancements and customizations in and around Koha by using mostly the existing configuration options.
	Amazon lookup script for Koha libraries
	We order most of our materials from Amazon, so I've been looking for a convenient way to tell if a book under consideration is in our catalog already.
	Greasemonkey & a custom user script fit the bill nicely:
	https://addons.mozilla.org/en-US/firefox/addon/748	https://addons.mozilla.org/en/firefox/addon/koct/
	http://userscripts.org/scripts/show/56847
	A few caveats:
	Like most scripts, this one was designed to work with Firefox; I haven't explored getting it to work with other browsers.
	I'm not a JavaScript programmer -- this was adapted from others' work. Just a few lines would have to be changed to get the script to work with your catalog.
	It depends on the existence of ISBN for the item in question, so movies, older books, etc. would not work.
	Others have added all sorts of bells & whistles: custom messages based on the status of items (on order, on hold, etc.), ... just search the UserScripts site for Amazon + library. For a later date!
	Keyword clouds	Palavra-chave:
	In addition to the traditional tag cloud available in Koha, there is a way to generate clouds for popular subjects within Koha.
	The :ref:`Author/Subject Cloud cron job <cron-subject/author-clouds-label>` is used to help with this process. This cron job sends its output to files.
	/home/koha/mylibrary/koharoot/koha-tmpl/cloud-author.html
	/home/koha/yourlibrary/koharoot/koha-tmpl/cloud-subject.html
	This means that you can produce clouds for authors, collective author, all kind of subjects, classifications, etc. And since it works on zebra indexes, it is quick, even on large DBs. Tags clouds are sent to files. It's up to library webmaster to deal with those files in order to include them in :ref:`OPACMainUserBlock <news-label>`, or include them into their library CMS.
	Some libraries even send the file into a Samba shared folder where webmaster take them, eventually clean them a little bit before integrating them into navigation widgets or pages.
	Newest titles pulldown
	Often we want to add a way for our patrons to do searches for the newest items. In this example I'll show you how to create a pull down menu of the newest items by item type. These tips will work (with a couple changes) for collection codes or shelving locations as well.
	First, it's important to note that every link in Koha is a permanent link. This means if I do a search for everything of a specific item type sorted by the acquisitions date and bookmark that URL, whenever I click it I'll see the newest items of that type on the first few pages of the results.
	I took this knowledge and wrote a form takes this functionality in to consideration. It basically just does a search of your Koha catalog for a specific item type and sorts the results by acquisitions date.
	The first thing I did was write a MySQL statement to generate a list of item types for me - why copy and paste when you can use the power of MySQL?
	The above looks at the itemtypes table and slaps the necessary HTML around each item type for me. I then exported that to CSV and opened it in my text editor and added the other parts of the form.
	Now, what does all of that mean? The important bits are these:
	First the starting of the form.
	This tells the browser to take any value selected and put it at the end of this http://YOURSITE/cgi-bin/koha/opac-search.pl. If you want to embed this form on your library website (and not on your OPAC) you can put the full OPAC URL in there.
