The management of electronic books or ebooks is very different than that of paper books of a lifetime. Here we talk about hundreds or thousands of files that we cannot physically touch and that we manage from our devices. For this, there are programs that help us greatly, such as the popular Caliber.
This is a software that has been accompanying us for many years and that has continued to improve and grow. To do this, in addition to correcting errors, new functions and features are implemented that significantly improve it. As many of you already know, from its interface we have the possibility of carrying out all kinds of operations with these ebooks.

In fact, and to give us an idea of what we are talking about, from here we can open, read, convert, manage, modify or buy these contents. In fact, we are adding books to one or more of our own libraries, which in turn include a multitude of administration functions. All this will be of enormous help to us when it comes to controlling hundreds or thousands of electronic books from Calibre in the best way. But of course, that huge amount of content takes up space, especially if we talk about thousands of ebooks.
That is why if we have certain space limitations on the PC, what is best for us is that our Calibre library does not take up too much disk space.

Divide the Calibre library into several
As we mentioned before, the same electronic book library in these times can be made up of thousands of titles. This is a lot of disk space in some cases, space that we might need for other system purposes. Therefore, to solve this problem, what we can do is create several of these independent libraries.
For example, we can divide the ebooks among them by themes, types of use, or needs. In this way, the libraries that we do not need at that time can be saved on external drives so as not to spend on the PC’s own hard disk.
Delete cover photos of ebooks
Along with the file of the book as such, whatever format it is, many times the photo of its cover is attached independently. This is usually a conventional photographic file, so we can always do without it. The ebook will remain the same, but the only thing we will not see is its cover when marking it.
If that is not something important to you, surely this elimination will save you a good amount of space in the Calibre library
Use the duplicate books feature
On many occasions, especially if the Personal Calibre library is very voluminous, we find a good number of repeated titles. Well, this program that we are talking about has a complement that we can activate that will be very helpful. And it is that it is in charge of helping us locate and eliminate those duplicate ebooks in the same library. Obviously this also saves space on the equipment .
Remove books from the Calibre library that we are not going to use
On the other hand, the most radical solution, but sometimes more than necessary, is to get rid of all those electronic books that we consider as expendable. In the event that we do not want to delete them forever from the Calibre library, we can always change their location and store them for the future. For example we can make a selection of these and save it on an external drive such as a USB memory .
