Library management and universal e-book converter. Caliber program. Library management and universal e-book converter How to open an e-book on a computer

Caliber is one of the most convenient e-book managers that will be useful both for those who prefer to read from a laptop or desktop PC screen, and for those who use portable devices for reading. For almost all popular "readers", the application has the necessary drivers, and the device is connected using a convenient wizard. In addition to specialized electronic "readers" like Pocketbook or Kindle Fire, the program also allows you to organize an electronic library of smartphones and tablets based on iOS and Android operating systems, and in general it supports almost all devices that allow, one way or another, to read books.

In addition to making it easy to manage downloaded books and transfer them between devices, Caliber also includes a built-in viewer, design tools, and allows you to edit metadata. The program did not do without the conversion function. It can be done either manually or you can instruct Caliber to automatically convert books to a supported format when transferred to another device. The list of formats supported by the application includes both common EPUB and TXT, and little-known ones like LRF and MOBI. In general, finding a book in a format that Caliber could not "swallow" is almost impossible.

And on top of all the above features, it is worth adding that the program can search online libraries and is completely free.


E-books are available for reading not only on real readers, but also on a computer running Windows. In the basic configuration, the OS does not accept such files and cannot open them. Notepad won't help either, but you can download Caliber or something similar and turn your PC into a real library. Caliber is the best solution, as it allows you to not only read, but edit documents. And for even greater comfort of work, support for archives is available.

How to open an e-book on a computer

Electronic books have entered our lives and replaced the real ones. If you want to get in on the action, you don't have to splurge on expensive devices when your Windows PC can do the same. And if you also have a tablet, then you can turn it into a full-fledged reader. Download Caliber is in two cases:
  • You want to open a document;
  • You need to make changes to it;
99% of all popular formats are supported. Even support for Amazon Kindle and various specific extensions for Android has been announced. Of course, the most popular type is also opened - EPUB.

E-book viewer

Most analogues only allow you to read. The maximum they can do is change the scale or remember the page where you stopped. This is good, but hardly enough, as it does not allow you to make edits or leave notes. All this is available in Caliber and it is the only free utility with such functionality. All analogues with him are paid. But you do not need them, and confirmation of the words in the video review:


But don't rely entirely on the ability to edit. Although it exists, it is primitive. You will be able to make adjustments to the metadata, change the cover slightly, and also leave comments on pages or entire files. This is all that is available to you, that is, you will not be able to rewrite or replace pages. But you will have this opportunity if you decide to expand the functionality using plugins. There are really a lot of them, because. they are released not only by official developers, but also by third-party amateurs, as well as in the case of

Since I am a big fan of reading, at some point my eyes fell on e-books. The benefits were obvious to me. Especially with frequent business trips. Weight, size, convenience, and the price of electronic versions of books (I prefer an honest purchase of texts). Having used several copies, I settled on the Sony PRS-505. At first I was confused by the lrf format, but the solution was quickly found - online fb2 to lrf converters. Online - because I am a Linux user both at home and at work, plus at home I use WinXP for games. In general, a complete mess. But when I started looking for books in English, I came across a bunch of other formats from pdf to epub and even more exotic options. Plus, there were a lot of books on computers and it became difficult to understand them (I'm not the only eBook user in the family). In general, there is a need for some kind of control over this chaos and convenient format conversion, plus native support for Linux. In one of the comments on Habré I saw a mention of Caliber. Downloaded, installed - liked it. Now I use it completely. Therefore, I would like to make a brief overview of this program.

About the program and its features

Caliber is a free and open source cross-platform application designed for e-book users with a lot of features.
  • Library management.
    Caliber gives you the ability to manage your book collection. The concept of the program - a lot of identical books in different formats are presented as one book in the library.
    You can sort and search books by metadata such as: title, author, publication date, date added, size, book series, rating, etc. There is also support for tags and comments and reviews.
    You can easily find the required book with a simple search or use the advanced search.
    The program organizes the books you add into a clear hierarchical folder structure on your hard drive, so that even in the absence of the program, you can sort through your library.
    Plus caliber can search the web for book metadata and cover art by title/author or ISBN. The metadata search system is defined by plugins and can be easily extended independently (With literature in English, it searches with a bang)

    The conversion has many options, such as changing the font size, creating the structure of the book and footnotes, etc.
  • Synchronization with readers
    Caliber uses a modular reader driver system that allows you to add new devices. Now the program already supports many devices. When synchronizing, Caliber chooses the most suitable format by itself, or if there is no necessary one, it converts it to the required one. It also adds all the necessary metadata and information about book series to the reader.
  • Download news and convert it into a book
    Caliber contains already 3 hundreds of news sources. And after reading the manual, it will not be difficult for you to add new sources

For Windows, everything is simple - we take the distribution kit and install it.
For Mac.
For Linux, we are looking in the repositories of your distribution, with a high probability there will be.
If you use something less common (in arch, for example, there is only in AUR) or we want to have the latest version, then run the script
