Calibre reviews and news :


WoW! Seven years after it was first released, the free ebook management software Calibre has reached version 1.0. According to the author (Kovid Goyal), lots of new features have been added to calibre in this new version — a grid view of book covers, a new faster database backend, the ability to convert Microsoft Word files, tools to make changes to ebooks without needing to do a full conversion, full support for font embedding and subsetting,  an easy to use tool to edit the Table of Contents in ebooks, rewritten PDF Output engine, new tool "Polish books" that allows you to perform various automated cleanup actions on ebooks.

DRM (Digital rights management) is a technology for access control that is used by ebook publishers and inhibits uses of ebooks that were not desired or foreseen by the content provider. When you buy an e-book with DRM you don't really own it but just have a permission to use it in a manner dictated to you by the seller. DRM limits what you can do with e-books you have "bought". Often people who buy books with DRM are unaware of the extent of these restrictions. These restrictions prevent you from reformating the e-book to your liking, including making stylistic changes like adjusting the font sizes, although there is software that empowers you to do such things for non DRM books. People are often surprised that an e-book they have bought in a particular format cannot be converted to another format if the e-book has DRM. So if you have an Amazon Kindle and buy a EPUB book sold by Barnes and Nobles, you should know that if that e-book has DRM you will not be able to read it on your Kindle.

is advertised as the one stop solution for all your e-book needs. But as one famouse person said "I suppose you could design a car that flies and floats, but I don't think it would do all of those things very well." That's why though Calibre is free, there are a lot of people that are not happy with this software and are looking for alternatives. Not for alternatives that also can fly and float, but for smaller and easier alternatives that can either fly or float and do it better than Calibre. We have picked 5 interesting apps in four categories that can replace Calibre on your desktop.

Kovid Goyal, the creator of the popular book collection management software Calibre created this video tutorial called "How to use Calibre - a look at its features and user interface". It shows some tips of how to optimize your usage of the program user interface. The main window interface consists of four areas: the book list (shows the books in your library), library browser sidebar (allows to browse your collection by various categories like series, publishers, rating...), book detail view (shows the book cover, formats available, comments..) and the upper search bar (allows to find books in your calibre collections). The user interface areas can be risized and hidden. You can also rearrange/hide columns in the book list. Watch the video about this robust library management software.

If you have a huge ebook library on your Nook and not all of these ebooks were purchased from Barnes & Noble directly, so you probably have rather challenging task of managing those books, since Barnes & Noble doesn't manage titles purchased from other stores. But now you have a solution.  The new version of the popular library management software Calibre (v.0.6.27) added support of Barnes & Noble Nook e-reader device. Calibre can now connect to  Nook on Windows, OS X and Linux. It scans the e-reader and adds ebooks to your digital library. Or, vice versa, you can send ebooks from your computer e-library to Nook. The software can also convert ebooks to/from EPUB and PDB, the two e-book formats supported by the Nook. Nook integration is realized via add-on driver.

Calibre is a new book collection software for Linux Ubuntu. It was started in 2006 by developer Kovid Goyal as a Linux application for converting different ebook formats to LRF - the format used by SONY reader and was called libprs500. This converter became wildly popular and was picked up and used by various publishing houses and content digitizers to produce the first generation of books in the LRF format. And in 2008 Kovid Goyal decided to transform the program to the full-featured e-book collection manager with graphical interface and renamed to Clibre. Using Calibre you can manage books, magazines, comics. Calibre is available in the Ubuntu Software Center, but before installation check that you downloaded the latest version (0.6). To install Calibre on Ubuntu and Linux Mint you need to execute the command line command that you can find in the Calibre for Linux manual.

My first inkling that something might be wrong was when I opened the program and it couldn't open it's own quick start guide. XP could not find an application that would open the file. I tried pointing it to calibre.exe (Windows does not list the program so you have to search for it) The program would add the guide to it's library but still could not access it. Wow!

Seems complete in its features. Detailed instructions on how to sync with iTunes allows me to manage my e-books on my new iPad3. Incredible free price!

seems like they feel the need to reinvent the wheel just to be different. Completely strange interface. Even though I selected in my settings to only import epub and pdf it tried to import practically EVERY file in my documents folder, not just books. weird. Also hangs up a lot on Window 7.

There is a new alternative to Calibre called Scida
It doesn't convert, but the interface is much better and easy to use.

Really difficult to understand software. But if it's really developed by one person - it's very impressive
