Few people know that it is actually possible to curate Wikipedia content into custom print books or PDF / OpenDocument ebooks that contain exactly the content you want in the order you specify.
Once you are logged into Wikipedia you simply activate the Book Creator Tool and then, from that moment on, everytime you visit a Wikipedia page you can click and add it to your curated Wiki-Book.
There is also a dedicated wiki page where you can manage the pages you have collected and you can reorganized and sort them any way you want, eliminating the pages you don’t need.
Unfortunately there is no integrated way to edit and further customize the content of those pages for your own use.
PDF versions are freely downloadable by anyone, print book versions are paid.
N.B.: The price for print books depends on the number of pages, starting with US$ 7.90 for books up to 100 pages. 10% of the gross sales price goes to the Wikimedia Foundation. Books are perfect bound, printed in the dimensions 8.5 inch x 5.5 inch (216 mm x 140 mm) and contain a table of contents, your chapters and articles, licensing information next to an index.
