Seven books, one viewer
A document can be a PDF, an EPUB, a Kindle book, a FictionBook, a comic archive, a folder of images or a folder of HTML pages. This is the front-end both packages ship, loaded the way the Joomla module and the WordPress shortcode load it. Everything happens in your browser.
Drag a corner to turn a page, or use the toolbar. Arrow keys, Home and End work once the book has focus. Search, contents and thumbnails are in the toolbar.
