Wikimedia, the company behind Wikipedia, has added a new export option to its site that allows you to save content in EPUB format, essentially enabling off-site reading to be performed on several eBook readers, including Amazon's Kindle devices.

The resource site has offered an option for signed-in Wikipedia visitors to collate their favoured articles into book form for a while, but this is the first time that that self-made tome (content specific encyclopedia, if you like) can be published into an eBook format.

You can also export the same book as a PDF or OpenOffice file, or even as a bone fide printed volume via PediaPress.

It's simple enough to do`; click on the "Create a book" option on the sidebar and, once activated, just tag articles and pages you want to store as you visit them. When you've got what you want, go to the export options in the "Manage your book" section and you can select the format for download. Voila! You can even reorder the pages to suit specific chapters, etc.

The firm has added the EPUB format for eBook readers because it feels that's the most natural way to read content offline. "EPUB files can be used very easily in an offline environment" said Tomasz Finc, director of Mobile at the Wikimedia Foundation. "They can be opened and distributed just like normal files. Plus, there are readers for almost every platform."
