CNET Editors' review
For those with certain e-reader devices, working with e-books on a computer can be difficult. Calibre for Mac is a free program that helps you manage your e-book libraries and create e-books from other sources for use on portable devices.
Calibre for Mac is an open-source freeware program, and it's easy to download and install. The initial setup is easy, but requires an e-mail address to link to the user's e-reader. Once this is done, the user is prompted to go to an outside Web site for more instructions on using the program, and some streaming demonstration videos. These covered the program generally, as well as specific, more complicated features. The interface is a little cluttered and confusing, making thorough reading of the instruction manual necessary. Fortunately, this popped up immediately after we started the program.
Despite the fact that the program is freeware, it offers functions beyond simply organizing and managing an e-book library. Calibre converts files between multiple e-book formats, allowing users to read books on different devices and even generate e-books out of Internet news sites for use in an e-reader later. It can also search out availability of e-books across many Internet sites.
For those with the time to work through its manual to learn all available features, Calibre for Mac may be a great option for e-book library management, especially considering that it's free.

"Ignore the bad reviews"
Version: Calibre 0.9.11
Pros
Free, quick to install, simple to use, and provides a wide range of tools with simple options.
Cons
As with any programs with easily customizable tools, spending five minutes reading the manual is necessary.
Summary
This is a great little program with a lot of options that seems to get regularly updated. I really don't understand the complaints about bad visuals or complex options. Are you familiar with computers, the concept of buttons, drop down menus, and directories? Then, you'll be fine. If you are only comfortable with dragging and dropping, you may be in trouble, but five minutes spent reading should cure that.
I downloaded it and installed it within five minutes and had converted 15 files and transferred them to my device within eight minutes of installation. No issues with formatting, but if I had, there are tools to adjust the formatting and a manual that explains these tools in detail.
As I have many books that aren't in a format for iTunes and my iPad, this will become my ebook library. -
"Fantastic application - difficult interface"
Version: Calibre 0.9
Pros
Converts to and from most any e-book format and does it quite well. Once you figure out how to use it, it's practically a "killer app" for e-book lovers.
Cons
It's tough to figure out how to use it. A tutorial, simpler interface, or something like it is needed to make it live up to its true potential.
Summary
This is a "must-have" program, but you really need to work with it for some time in order to figure it out. Not everyone has that much patience.

"cross-platform implementation on the Mac makes no sense"
Version: Calibre 0.8.61
Pros
probably works, but
Cons
Fails to automatically look at original document, to then set conversion defaults. The result is a document with lines too long or too short.
The bigger problem is that this doesn't work like other Mac programs, you can't drop a file on the application, it takes FOREVER to load, and there is no obvious logic to follow to change a .PDF file to an eBook.Summary
I'd be delighted to pay real money to someone who turns the underlying engine into a real Mac program.

"Below average"
Version: Calibre 0.8.55
Pros
Converts small files well
Cons
Unable to convert large files,
My computer becomes soooooooooooooooooo slooooooooowSummary
Some good features, but need a bit of upgrade
-
"Killed my Kindle"
Version: Calibre 0.8.51
Pros
I have nothing good to say about it.
Cons
I converted the e-book file to be kindle-compatible, and then installed it on my kindle. It basically killed my kindle, and I am unable to start it up. I've tried all the tricks to get it working again, but to no avail.
Summary
Big mistake.
-
"Useful but Ugly"
Version: Calibre 0.8.8
Pros
Converts to different ebook formats
Cons
GUI and Icons could use some work
Summary
You can convert from and to different formats; epub, mobibook, pdf, etc..
Needs a better looking interface and icons. Try to get a mac designer to work on this. -
"Important functionality but confusing array of options"
Version: Calibre 0.8.4
Pros
Allows filing as well as access
Cons
non-intuitive interface
-
"Outstanding program for its use."
Version: Calibre 0.7.50
Pros
Easily imports books, no matter their formatting. Even works with ebooks which are not designed for an electronic reader. Allows reformatting to meet your needs. Can, in most cases, retrieve the metadata for your ebook.
Cons
If you aren't careful with your settings and selections, if you can delete your files without realizing that your doing so until their gone. Be sure to read the online program manual or you may be sorry.
Summary
I have thousands of digitized books in PDF format on my old Mac which I thought I was going to lose. This program allowed me to batch convert these files to text files which I will be able to use on whatever system I get to replace my dying computer.

"Good tool, bad interface"
Version: Calibre 0.7.49
Pros
Offers eBook conversion, allowing us Kindle types to convert ePubs, etc.
Cons
A clearly "cross platform" interface, keeps its files in odd places, insists on running as a library rather than merely a tool.
Summary
A fantastic quality tool for free, but insists a little too much on trying to become the centre of your electronic book collection.

"unusable - won't open"
Version: Calibre 0.7.48
Pros
none that I could ascertain
Cons
unusable - I get message " You cannot open the application "Calibre" because it is not supported on this architecture"
Summary
waste of download time
