Calibre 3.0 Released

Que the marching band, drum majorettes, and confetti cannons: Calibre 3.0 has left beta and was officially released last week.

Initially released in 2006 as libprs500, calibre has grown from humble origins as a set of USB Linux drivers for the original Sony Reader to become the leading free and open source ebook library tool.

It took seven years to reach the 1.0 release, another year to reach 2.0, and now three years to reach this latest milestone.

Calibre 3.0 Released calibre

Calibre supports all manner of ereaders, tablets, and smartphones, and can convert to and from more file formats than can be listed here.

One of the reasons I like (besides being able to auto-convert dozens of files at a time) it is that it is a great tool for stripping DRM. That's not one of the official features, no; it's just one of the many improvements mad by the 3rd-party developers who contribute plugins to calibre.

Other nifty features include downloading and delivering news articles, reading ebooks aloud, acting as a content server on a local network, and creating or breaking up omnibus ebooks.

How do you like to use calibre?

Nate Hoffelder is the founder and editor of The Digital Reader:"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."

  1. I use it because I’ve changed brands of e-reader over the years and have the same consistent method of getting books onto them.

  2. Does A. Alf still work with this new version?

  3. i use calibre pretty much constantly.. great program.

  4. The tools worked with the beta release and had no problem using the calibre 3 release today.

  5. I use it for OverDrive just downloaded a new plugin today for that for ver 3.0 great program !!

  6. How do you strip the DRM from Kindle and Nook books using Calibre?

  7. Might be nice to eventually update those instructions. Also, a guide for how to upload from calibre to various readers WHILE MAINTAINING YOUR ORGANIZATION (ie sorting by genre, series, etc) would be really nice.

  8. The absolute best ebook program. I use it on Windows & Linux, tell everyone I know about the program, donate – you name it. And the improvements over the last few years have been better than most commercial software programs!

  9. I just thought you might want to correct the first word, which should be “cue” rather than “que”. There are two words with that pronunciation, “cue” and “queue”, but you want the first one.
