Calibre facilitates the management of your ebooks effortlessly. This is possible due to the steps we detail below.

Adding Books to Your Library

Calibre provides several options for adding new books to your library.

Calibre Add Books
  • Add books from a single directory: this option lets you choose to add books from a specified directory.
  • Add books from directories and sub-directories: this lets you select a directory as an ebooks source. This option essentially scans a directory and all of its sub-directories for ebooks and adds them to your library.
  • Add multiple books from archive (ZIP/RAR): with this option you can add ebooks that are stored within ZIP or RAR archives.
  • Add empty book (Book Entry with no formats): this option allows you to create a blank book record and is useful if you don’t have a book in your collection. You can fill out the information relating to it to have it as a reference.
  • Add from ISBN: this option lets you add a book from its ISBN number.
  • Add files to selected book records: this option allows you to add or update the files associated with an existing book record.
  • Add an empty file to selected book records: this lets you add an empty file to a selected record.

After selecting the option that suits you best, simply select the books you need for them to be available in your library. You can also just drag and drop books into your library.

Removing books is as simple as selecting the book(s) you want to remove and selecting the “Remove books” option.

Sidebar Interface

You’ll find a few filters in Calibre’s sidebar that allow you to quickly sort through your books when you’re looking for a particular book or category of book.

Calibre Sidebar Filters

The filters included by default are:

  • Authors
  • Languages
  • Series
  • Formats
  • Publisher
  • Rating

Editing Metadata

Calibre usually gets this right, but sometimes the metadata isn’t quite right when a book is imported. Easily edit this by selecting the “Edit metadata” option. Edit information such as the date a book was published or add comments. The more information that you have entered about your books, the easier it will be to find and manage them.

Transferring Files to Device

If you attach a device such as an ebook reader, a phone, or a tablet to your computer running Calibre, a Device button will appear that lets you send books to your device.

Sharing Books and Backing Up Your Library

This management software comes with powerful sharing and backup features. It’s one thing to have a nice library collection, but the ability to make it accessible is another story. You can set up a content server quickly and easily that lets you access your books from any device with an Internet connection. To start the connection, simply select “Start Content Server” under the “Connect/Share” button.

You can then access your library from other devices connected to your home network. To do this, you’ll need to enter the IP address of the computer you’re running Calibre on, along with the port number assigned to Calibre. This information is displayed next to the “Start/Stop Content Server” button. For example, if your IP address is and your port number “8080,” then you can access the content server by typing

into a web browser on a device connected to your home network. If you’re accessing the content server from a computer outside of your home network, you’ll have to go into your router settings and forward the port that you assigned to Calibre.

Calibre Sharing Browser

You can also share books via email with Calibre. In addition, there is a Calibre Companion app available for iOS and Android that lets you access your Calibre library.

Calibre Companion

It allows you to access your library via the content server or the “Start wireless device connection” option in Calibre. You also have the option of connecting to a cloud service.

To back up/restore your libre, click on the drop-down arrow attached to the Calibre Library and select the “Export/Import All Calibre Data” button.

Editing Books

Calibre also gives users the ability to edit ebooks. Specifically, you will be able to work with EPUB and AZW3 files. This could be useful for adding notes to yourself in books.

Avid readers need a powerful tool on their computers to manage their eBooks. With features like the ability to convert to and from multiple formats and the ability to add custom filters, Calibre fits the bill perfectly. You are also not limited to just using it on a computer, thanks to the content server option and the companion app. Give Calibre a try if you want a powerful, simple-to-use, and free ebook management application.
