Manage, view and convert your e-book collection

Is your e-book collection is a disorganised mess of different formats and competing viewers? It doesn't have to be that way. Calibre is an e-book management tool that will quickly bring order to the situation, and help you get more from the format, and (if you have one) your portable e-book reader.

The process starts by letting the program organise your e-books library. Point calibre at your files and it'll quickly (and almost automatically) build a database around your collection, downloading metadata like covers for extra visual appeal. You can then sort and search your books by title, author, date published, rating, custom tags and more, making it quick and easy to find whatever you need.

Calibre can then display your book, too (as long as it's not DRM-protected), with an integrated viewer that handles all the main formats and supports features like table of contents, CSS, printing, searching, embedded fonts and more.

You also get a comprehensive conversion tool that will convert documents in all the main e-book formats (CBZ, CBR, CBC, EPUB, FB2, HTML, LIT, LRF, MOBI, ODT, PDF, PRC, PDB, PML, RB, RTF, TCR, TXT) to any of twelve standard formats (EPUB, FB2, OEB, LIT, LRF, MOBI, PDB, PML, RB, PDF, TCR, TXT).

And there are many surprising extras. Calibre can automatically fetch news from websites or RSS feeds, for instance, then format the results into an eBook. A powerful sync tool will work with many different devices, from dedicated e-book readers like the Kindle to Android phones and the iPhone. And the program even includes an integrated web server that allows you to access your e-book collection from a browser, anywhere in the world.

Version 2.40.0 changes include (release notes):

    - A new tool to apply Tag mapper rules to existing books in the library. To use it, go to Preferences->Toolbars and add the tool to the toolbar. 
    - Kindle driver: Detect books in Amazon's new KFX format present on e-ink kindles.


If you've any kind of non DRM-protected e-book collection then you need this amazingly versatile and feature-rich management application. Go download it immediately

Calibre E-Book Viewer & Converter

Posted by: Nicholas Jones, 17 February 2012 18:53

This is really good. I've used this for ages. Will let you read just about any format of e-book, ever produced. As far as converting goes, you must be realistic. PDF to TXT is not going to work well! But basic converting present no worries, although I wouldn't lose sleep of the quite bewildering array of option, that have been stuffed into this piece of kit. This one piece of software were reading through the HELP files, will, er... definitely help.

WhatsApp Messenger 2.12.7

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.7 brings:
