If you received a notification concerning the ligatures in your file - which often causes readability issues in the Kindle app - you should turn off ligatures in your file and reupload it. You may need help from your production team to do this.

Turning Off Ligatures

If some characters are not rendering correctly - especially ff, fi, th - it's either because of embedded fonts, or ligatures have been enabled within the originating document. Ligatures in text do not render properly after they have been converted to Amazon's own proprietary format.

How to turn off ligatures in InDesign:

  • In Advanced Mode, go to Paragraph Styles. You can also go to Windows>Styles>Paragraph Style or press F11 to call out Paragraph Style window.
  • Edit your basic paragraph style or any other paragraph style you have.
  • Under the Paragraph Style Options window> Basic Character formats> uncheck Ligatures.

If you have a content file that prevents the book from being made available in the catalog, accessed by members, or causes difficulty for the members who are reading the book, you will receive a notification from the NetGalley team that details the problem. You will see this notification on the title details page, and in an email sent to your "File Import Notices" email address (found in the Settings of your Publisher Account.)
