Reading your favourite articles on Wikipedia, offline, is now very easy to do, thanks to the Book Creator feature that Wikipedia has added to its website.
What this does is very simple, it allows you to compile your favourite articles and export them to PDF, OpenOffice and my favourite, Epub.
To get started, open any page on Wikipedia, and on the right pane, click on Print/export | Create a book | Start book creator. On any page you visit that you would like to read offline, click Add this page to your book on the top of the page.
When you are through with your compilation, click on Show book at the top of the page, give your book a title, rearrange the pages and export into any eBook format of your choice.
Load the ebook into your mobile device, kick back your seat and enjoy a nice read.
