Create and download your own ebook from pages and namespaces offered.
To use this feature, any page you are currently viewing can be added to a book. Using the menu to the right-most (Pen icon), use the Add to book option. Do this for every page you wish to be added to your download. Upto about 80 pages can be added.
For PDF to work, your browser must support this feature. Printable version lays the page out to make it suitable to print. ODT gives you HTML for that page!
This feature is mostly untested and has been added to demonstrate possibilities of custom ebooks for your needs.
