Calibre Comments

Great interface, yet too heavy

Comment by halliganjosh
about Calibre Feb 2016

I first started using Calibre whilst playing around with some applications for digital book keeping. At first, not only did I find it useful in the regard that it could open any type of book format for free. No premium version needed. Simple, straightforward interface, but after some time I did notice it started to slow my computer down a bit and make it very heavy. Ended up uninstalling it but was good while it lasted.


Basically useless

Negative Comment by RebeccaWhit3
about Calibre and Blio Feb 2016

This software forces you to copy your entire ebook collection into a single directory. The developers aren't willing to consider anything else. Additionally, it doesn't modify the original files. So literally, this software will — without confirming with the user — duplicate your entire reading collection.

I've used the application for a number of years now and am abandoning it for good now. Can't believe this software won't let you manage a collection manually. I don't know about other users, but my reading collection contains both fiction and educational material, which I've spent a great deal of time organizing to be accessible. I'd love to use this application but it's just not possible unless you want to mix EVERYTHING you have into one folder. Yet another application that could be 100x better with little to no change but wont because the developers are religiously bound to a flawed approach to ebook management.

I recommend using another application called Blio for personal reading needs. It also has a flawed approach to file management, but it makes up for the fact with looks.


Great app!

I don't know how people with an ereader could survive without this software.

It is amazing, I love it!!


Hands down the best eBook manager out there.

about Calibre May 2012

I've been using calibre for about a month now (since I got my Kindle). It does an amazing job of organizing and converting eBooks. It even tightly integrates with my Kindle (organizes collections, converts for reading on Kindle). No e-reader owner should be without calibre.

Oh, and don't forget to donate when you fall in love with it.


Good Choice
