In recent years, the number of bookstores has decreased and e-books are becoming the inevitable future. Reading on a desktop or laptop is popular with students and professionals alike thanks to the larger screen size.

While the usual word processor installed on your computer would be sufficient to read documents, it doesn't do the book lover in you justice. So here are five e-book readers for your Linux system that are perfect for a casual reading session.

Caliber is the perfect candidate to start with. This wonderful tool is not just an e-book reader, but a complete suite for all of your e-book needs, a one-stop solution. It's also completely open-source, free to use, and a cross-platform tool that is of course available on all major operating systems such as Windows, macOS and Linux.

With Caliber, thanks to the wide range of accepted input formats, you don't have to worry about opening a certain type of e-book: AZW, AZW3, AZW4, CBZ, CBR, CB7, CBC, CHM, DJVU, DOCX, EPUB, FB2, FBZ, HTML, HTMLZ, LIT, LRF, MOBI, ODT, PDF, PRC, PDB, PML, RB, RTF, SNB, TCR, TXT, TXTZ.

Caliber's features and functionality go way beyond what a regular e-book reader can, so you can do several cool things with Caliber.

If you are looking for a single application that can meet all of your ebook viewing, editing, converting and creating needs then look no further. However, if you find these features a little extra for your needs, the upcoming readers on this list could be just what you're looking for.

Foliate is a simple but modern and feature-rich e-book reader for users who don't need the bells and whistles of caliber. Foliate focuses on being an e-book reader rather than a complete solution while having all of the features you are looking for.

Like all of the other e-book readers on this list, it supports all popular e-book file formats like EPUB, Mobipocket, Kindle, FictionBook, and comic book archive formats. In addition, it offers many customization options for layouts, fonts, spacing, colors, and more.

You can expect all of the popular features you would find in an e-book reader, such as: B. a table of contents menu, progress slider, chapter markers, reading time estimates, zoom settings, footnotes and trackpad gestures. You can also open multiple books at the same time or open the same file in multiple windows.

The bookmarks and annotations combined with the nifty built-in tools such as looking up words in Wiktionary or Wikipedia, translating passages with Google Translate and text-to-speech give Foliate an edge over its competitors. You can also export your bookmarks and annotations in plain text, HTML or Markdown.

The name pretty much gives it away. Bookworm is a simple and focused e-book reader with just the right amount of features for the bibliophile in you. It supports most of the popular e-book formats like EPUB, PDF, MOBI and more.

Bookworm is currently being developed for Elementary OS, but will be distro-independent in the future. However, that doesn't mean you can only use it on Elementary OS. It is available as a PPA for Ubuntu, as a package for OpenSUSE and as a flat package for other Linux distributions.

Bookworm has a simple and easy-to-use layout that supports three reading profiles for light, sepia and dark, in addition to other common functions such as increasing / reducing text, increasing / reducing the margin, and increasing / decreasing the line width.

For more customizations that Settings Tab gives you options to enable night mode, enable cache for faster subsequent reading, library view, custom reading profile, and automatically import e-books from a folder.

Buka is a clean and minimalist e-book reader created by the same developer who created the Stacer Linux optimizer. It has a simple user interface and is designed to provide an enjoyable reading experience without any problems or concentration on the content.

There is only one caveat, however: only PDF files are currently supported. If you want to read eBooks in other formats, you can skip this one. Otherwise, Buka can be an ideal choice for you. Why? Check out some of the features listed below.

Buka has a simple user interface suitable for all ages with a dark theme for reading at night. It has all the basic features like keyboard navigation with arrow keys, page zoom, search box and the ability to categorize books in custom lists.

Interestingly, Buka also comes with a built-in translator tool to translate the passages or text fragments into your preferred language. If you normally only read PDF files, give this reader a try.

If you have been using the KDE desktop environment for a long time, you may be familiar with Okular, the standard document viewer. It is a feature rich viewer that you can use to read PDF documents, comics, EPUB books, search through images, visualize Markdown documents, and much more.

With Annotation mode, you can underline, highlight, or add your own text, making it perfect for taking notes. The Selection mode allows you to select text, a range or even a table from any document and copy and paste it anywhere.

If the text you want to read is too small, you can use the Magnifying glass mode. Okular makes navigating the document child's play with the Thumbnails Panel for visual navigation and the content Panel for chapter-based navigation.

You can view and review digital signatures embedded in PDFs, verify that they are still valid, and see any changes since the time the document was signed. You can even sign PDFs yourself.
