An electronic book (commonly abbreviated e-book) is a text and image-based publication which can be read on a computer or other digital devices such as an e-book reader.
Digital books are well established. Project Gutenberg, an online library of books that can be downloaded free of charge, has been expanding its collection since 1971. Almost its entire library consists of books that are available in the public domain, although there are a few copyright texts which are also included.
The popularity of digital e-books has been accelerated by a number of dedicated portable e-book readers. The various Amazon Kindle are extremely popular devices which have enabled readers to conveniently access a huge library of books, magazines and newspapers on the move. What is particularly noteworthy is that Linux is the operating system that runs the devices.
Sturm Reader is an ebook reader for Linux tailored for Ubuntu Touch and portable devices. This is free and open source software.

Sturm Reader is a lot more than just a competent ebook reader. It also offers full support for PDF files although page flipping isn’t quite as seamless as I’d like.
Additionally you can also view CBZ and CBR files, a type of archive file for the purpose of sequential viewing of images, commonly for comic books.
There is no support for DRM protected e-books.

I evaluated Sturm Reader with the Volla Phone Quintus, a smartphone powered by the Mediatek Dimensity 7050 with 8 cores, 8GB of RAM and 256GB of storage, running Ubuntu Touch 24.04.
