Thorium Reader is a free ebook reading app developed by the European Digital Reading Lab (EDRLab), a non-profit software development organisation specialising in digital reading and publishing. It's like Adobe Digital Editions, though perhaps a little easier to use. It's also European, which might interest non-Americans who wish to reduce their use of American big-tech software

it can open a variety of ebook formats and has a number of useful features:

  • Notetaking, highlighting and bookmarking
  • Adjusting text size, font type, line spacing, layout and background colour 
  • A read aloud feature which lets you listen to the text

Thorium Reader has better accessibility features than Adobe Digital Editions. It is fully usable with keyboard alone and supports navigation and reading with popular screen readers.

Thorium Reader is now required to read downloaded EBSCO ebooks. EBSCO ebooks use a DRM standard called Licensed Content Protection (LCP). Thorium Reader can open any LCP-DRM-encrypted e-book from any provider. 

At the time of writing, mobile apps for iOS and Android are in development, which makes reading downloaded ebooks on mobile devices tricky.
