When we have a virtual library of several thousand books it is inevitable to have duplicate books.
If we use Caliber for managing our library, It is very simple find and remove these libros, ebooks, repeated. We just have to install the plugin "Find Duplicates"
How to install Find Duplicates
We leave the tutorial made with Caliber 4.99.4 Find Duplicates version 1.10.7
The first thing we are going to do is install the plugin find duplicates. For this we are going to Preferences
And we enter Accessories
A window will open where we can search for the add-ons we have installed to manage them (update, delete, etc.) or install a new one.
In our case we are going to Get new plugins
In the new screen you just have to look for Find Duplicates above, select it and click on Install
We will get several notices to grant permissions that we have to accept and that's it. We already have our complement Find Duplicates installed in Calibre. Now we just have to see how it is used for find duplicate ebooks in our library.
How to find duplicate ebooks in our library
Open the plugin options. An icon will have been installed in the top bar of Calibre. If you don't see it, it's because it's hidden because Calibre doesn't show 2 rows of icons and you just have to open the dropdown
This will show us the icon and clicking on it will open multiple search options for duplicate ebooks
When clicking we will see the options with which we can play
The normal thing is to Search for duplicates of books and the following screen appears. It allows us to search for repeated books by Title, ISBN, or by binary comparison.
We can also search for library duplicates
We do a search with the option of books and it shows us two duplicates
We just have to delete one and that's it.
There are many options in the plugin to continue testing and squeezing it thoroughly.
