In the following you find a detailled description how EPUBReader works.

If you like EPUBReader, I would be very happy if you support it by a via PayPal.

Opening ePub-files for reading

When you have EPUBReader installed, you are ready to read ePub-files in Firefox. There are two ways how you can open an ePub-file for reading:

  • Go to a website where ePub-files are offered for downloading and click on the download-link. Please be aware, that EPUBReader only supports ePub-files without DRM protection. These websites are good locations to get many free ePub-files: www.feedbooks.com and www.gutenberg.org.
  • If you have already stored an ePub-file on your disk, you can open it via the Firefox menu "File/File open" or by dragging the ePub-file on the Firefox window.

EPUBReader downloads/opens now the ePub-file, makes some processing and displays the ePub-file ready to read. Depending on the size of the ePub-file, it may take some seconds until you can read it. When processing is finished, your screen looks like this:

Reading ePub-files

EPUBReader has opened the first page of your ePub-file. On the right side you see the content of the first page, at the bottom on the right side you see the navigationbar, which is describe in the following.

Navigationbar

  • Catalog-button. If you click on this button, the ePub-Catalog is opened. See below for more details.
  • Save-button. When you open an ePub-file with EPUBReader, the ePub-file is downloaded and stored in your Firefox profile folder. By clicking on the save-button, you have the possibility to store the ePub-file at a location of your choice.
  • Bookmark-button. If you click on this button, your current reading position is saved. If you open the ePub-file again from your Library, the file is opened at this position.
  • Navigation-buttons. If you click on the left or right navigation-buttons, you go to the previous or next chapter. If you just want to read the ePub-file from the beginning to the end, page after page, these buttons are all you need, you don't need to go to the TOC. The TOC is like the TOC in a book, it offers an additional possiblity to jump directly at various places in the ePub-file.
  • Zoom-buttons. If you click on the zoom-buttons, you can decrease/increase the font-size.

Table of Contents

On the left side of the opened ePub-file you see the table of contents. The table of contents is a list of links, which gives you the possibility to jump directly to a specific position in the ePub-file. At the bottom you find the following two buttons:

  • Preferences-button. If you click on this button, the preferences window is opened. You can change here the appearance of the book content and the Table of Contents. Check here for more details.
  • Help-button. If you click on this button, the FAQ-page of EPUBReader's homepage is opened.

ePub-Catalog

In the ePub-Catalog you have access to your private library and to the OPDS-catalogs of different websites.

Private library

Everytime you download an ePub-file on a webpage or open a local stored ePub-file, an entry to the library-page is added. If you want to read the ePub-file again, just go to the library-page and open it from there. The ePub-file opens faster than the first time, because no processing is done.

  • Open book. If you click on this button, the ePub-file is opened for reading.
  • Save. If you click on the save-symbol, you can save the ePub-file, which is stored in the EPUBReader-library, at a location of your choice.
  • Trashcan. If you click on the trashcan, the ePub-file is removed from the library-page and also from your Firefox profile folder.

The catalog can additionally be opened via the Firefox-menu "Tools/ePub-Catalog". Also a bookmark has been added to the end of you bookmarklist with which you can open the catalog.

OPDS-Catalogs

You can here access OPDS-catalogs of different websites.

Select the website in the listbox at the upper left. On the left side you can navigate through the catalog. If you click on the magnifier, you can see more details about the ePub-file. If you click on the book, you can open the file for reading.
