Chrome extension for creating html 'book' from wikimedia pages
I am involved on behalf of W3C with some European research projects where we are using a wiki to collaboratively work on reports for project deliverables. To assist with preparation of the final form of the report, I have created a cross platform Chrome browser extension that adds a context menu item to create and download an HTML file with the combined content from the current page and all of the wiki pages it links to. You can then export to PDF via print to PDF if your browser supports it, or with tools like PrinceXML. The extension and information on how to use it is available on the wikibook page.
