"EPUBReader is a Firefox addon which let you read ePub-files just in the browser. You don't need to install additional software!
If you click on a link to an ePub-file, you are normally prompted by the Firefox "save as" dialog. With EPUBReader installed, the ePub-file is downloaded, processed and directly displayed ready to read!"
"E-readers are the digital devices that put a library in a reader's hand and sometimes can be a direct line to newspapers and magazines. Some can download a book wirelessly in less than a minute and hold 1,500 volumes. Some can file away music. Some can be a repository for photographs."
Do you know that you can directly save any Wikipedia page as a PDF file without requiring any extensions or print drivers. In fact, you can even collect multiple Wikipedia pages in a basket and convert them all to a single PDF document (just like an ebook) with just a few mouse clicks.
