Calibre is an ebook management software.
- A Window or Linux computer. MacOs should work as well but was not tested.
- A Kobo eReader. The instructions should work for any Kobo of the touch, Glo, Mini and Aura families.
When the firmware of your Kobo is updated, you usually need an up-to-date Calibre to be able to synchronise your eBooks. For this reason, it is recommended to not install from your Linux distribution but directly from their website.
To install, go to https://calibre-ebook.com/download and follow instructions.
The first time you run calibre you will be asked a few question. The most important is the location of your library. Calibre will use this folder to store al the eBooks that you add to it.
Calibre will allow you to send ebooks to your Kobo without any configuration. However, the following plugins will enhance your experience.
To install them, go to Preferences → Plug-ins → Get new plug-ins, select the plugin in the list and click Install.
KePub Metadata Reader / KePub Metadata Writer
These two plugins don't provide any features. They are just used as dependency by KePub Output and KoboTouch Extended.
Kobo readers are using Kepub files. Those are similar to standard Epub files but support additional functionalities.
This plugin allows conversion of ebooks to the kepub format.
This plugin replace the kobo driver that comes with Calibre, it allows the conversion to Kepub format transparently when you synchronise with a Kobo eReader.
The kobo eReaders are including an analytics feature. In particular, they collect the infos on all the books that you put on your reader — including the ones that you didn't purchase from them.
This plugins allows to block analytics events
- Connect your eReader to your computer
- Click on the arrow near the KoboUtilities icon and select Database → Block Analytics Event
- In the window that opened, select Create or change trigger and click Ok
eBooks with DRM
When you buy an eBook from most major online book stores, they are likely to be protected by DRM. This has two major consequences.
- You won't be able to convert your eBooks to the Kepub format. This mean that advanced features not be available unless you buy your books on the Kobo store
- You might not be able to read the book on the device of your choice
- If the book store ever stop its operations, you might not be able to read your eBook at all
Fortunately it is possible to remove DRM from books allo.ing you to use the file that you legally purchased.
|Warning:||Removing DRM from the eBooks you purchased is illegal in some countries. Check the law before doing it. Do not share your eBooks illegally. Tagging technologies allow publishers to find the original purchaser of an eBook. You have been warned!|

eBooks From Other Book Stores
You can buy eBook from any book store that sell them in ePub. When those books are protected with DRM, you will need to use Adobe Digital Edition to download them.
