[edit] History
Kovid Goyal started developing libprs500 on October 31st 2006, when the Sony PRS-500 was introduced. The main idea was to enable the use of the PRS-500 on Linux. Kovid Goyal, with support from the MobileRead forum, reverse-engineered the proprietary file format LRF. During 2008, the name was changed to calibre.
[edit] Features
e-books can be imported into the calibre library, either by adding files manually, or by syncing an e-book reading device.
calibre supports all the currently commercially relevant file formats and reading devices. Most of these e-book formats can be edited, for example, by changing the font or the font size and by adding a auto-generated table of contents. As well as editing, printing is also supported.
calibre helps to organize the personal e-book library by allowing the user to sort and group e-books by metadata fields. Metadata can be pulled from many different sources (ISBNdb.com, Google Books, Amazon, LibraryThing). Full-text search, including the whole library, is possible.
On-line content-sources can be harvested and converted to e-books. This conversion is facilitated by so-called "recipes," short programs written in a Python-based domain-specific language.
E-books can then be exported to all supported reading devices via USB or via the integrated mail-server. Mailing e-books enables, for example, sending personal documents to the Kindle family of e-book readers.
The content of the library can be remotely accessed by a web browser, if the hosting computer is running. In this case, pushing harvested content from content sources is supported on a regular interval (subscription). If the hosting computer is not always on, a hosted calibre solution[1] can help. In this case, the library is not accessible, but the subscriptions are pushed to the reading device on schedule.
[edit] Development & License
The application is written in Python and C. It is published under GPL V3 GNU General Public License (GPL) as free Software and open source software.[2]
To convert external content sources calibre supports the RSS-Feedreader protocol; for remote access a E-Mail- and Webserver (HTTP) is supplied.
