To show our respect to this software and introduce you more eBook tricks, we are planing to compile a series of articles about how to use Calibre to do magics on eBook reading process.

Today it goes to how to transfer eBooks with Calibre, and I will divide this article into 2 parts: Transfer from computer to eReader, and from computer to another computer.

Transfer eBooks from computer to eReader

1 Transfer eBooks via Calibre Content Server

Calibre Content Server is my favorite method to transfer books from computer to eReader like Kindle and iPad, as this method allows me to get rid of those annoying wires.

To use this method, you should satisfy the following conditions:

Both the computer and eReader are connecting to the same network;
The eReader must have a web browser.

If you are not able to meet any of the demands above, please jump to the next method.

Step One: Load the book into Calibre. Just drag the book into Calibre's interface you can make it.

Step Two: Click "Content/share" --- "Start Content Server". Then the 3 blue buttons on the icon will turn green, and you can see [Your IP Address: Port] besides "Stop Content Server".

Step Three: Open the web browser on your eReader or tablet, and visit the [Your IP Address: Port]. For example, upon the information showed in the image above, I should visit []. And notice: everyone will get a different number, so do not just copy my IP address.

Step Four: Press "Newest" or "All books", you will see all the books which loaded into your Calibre library but sort by different rules. Click the "Get" button below book cover you can download it onto your Kindle, iPad, and other reading devices.

2 Transfer eBooks via USB cable through Calibre

This method is more universal than the previous one, but it needs a USB cable.

Step One: Plug your reading device to computer with USB cable, then some changes will happen in Calibre's navigation bar. There will be some new buttons like "Send to Device" and "Device", if Calibre doesn't detect your device, maybe it is not supported by Calibre yet, for this situation please contact Calibre for a solution.

Step Two: Choose the books you want to transfer in the library window below, then click "Send to device" button. If the book's format is not acceptable by your device, Calibre will ask if you want to convert the format. Click "Yes" and Calibre will convert and send them into your device.

Step Three: Calibre will not send you an obvious notification after finishing the job, however, if the remaining jobs number stays "0", it indecates all the jobs are done. Now click "Device" button, you will see the books are displayed there.

Step Four: Eject your reading device, and check if the books are transferred successfully.

The three books are just exactly what I transferred, now I can read them on Kindle freely.

Transfer eBooks from computer to another computer

In my hours of studies, most of people who want to transfer eBooks to one computer to another means transfer the entire Calibre library. Therefore I am going to mainly introduce how to transfer Calibre library onto another computer.

If you just want to transfer some of them, please follow the server content method.

Step One: Locate your Calibre library. Click Calibre icon in the navigation bar, you will get the information where your books are saved.
