Formats and Compatibility

• Which eBook formats are available on abc.nl?

  Depending on the title, the following formats may be available: Adobe DRM-protected EPub or Adobe DRM-protected PDF.

  EPub is the standard eBook format that makes it possible to optimise and customise text and images for both large displays like a desktop computer and small screens like smartphones. Sometimes the format is also referred to as 'flowing text'.

  PDF (Portable Document Format) is the standard format for document interchange created by Adobe.

  Both formats are "Adobe DRM Protected" and must be linked to a ByteBooks ID.

• What does DRM-protected mean?

  Adobe Digital Rights Management (DRM) ensures that the person who downloads an eBook is its sole owner and is unable to share the file with others. The DRM specification for each eBook is set by the publisher who owns the respective copyrights.

  In order to read DRM protected eBooks on any device you'll need to create a ByteBooks ID and install (and authorize) software that works with the ByteBooks ID.

  We recommend Adobe Digital Editions.

• Will the eBooks work on Apple products?

  Yes, as long as the sofware you use has been authorized with your ByteBooks ID. When you use any one of these apps for the first time you will be asked to enter your ByteBooks ID and password.

  Adobe DRM protected eBooks cannot be opened with iBooks.

  Adobe Digital Editions (ADE), our recommended software, is also available for Apple products.

• Can I buy eBooks for my Kindle?

  No, the Kindle is a 'closed' device so only content bought from Amazon can be viewed on a Kindle. DRM-protected eBooks cannot be loaded onto it.

Purchasing and Downloading

• How do I download my purchased eBook?

  Important: be sure to have authorized your ADE (or third party) software with your ByteBooks ID before you download your eBook.

  • After completing your order at abc.nl you will receive separate emails for every eBook purchased which contain a download link.
  • Click on this link to download a file with file extention .acsm. This is the licence that retrieves the eBook file.

  • In this program the actual eBook file will then be downloaded and added to your libary.
• How many times can the eBook be downloaded?

  The download link can be used successfully six times.

  Once this limit has been reached the eBook cannot be downloaded again. If the download limit is reached a notification with 'Download limit exceeded' will be displayed.

  The links are valid for a period of two years from the date the order is made.

  • If you did back up your eBooks, but did not register the ADE prior to their original download, then the eBooks will be tied to the old PC and will not work on the new PC.
