How to merge two libraries in Calibre?

[MonicaOP]

Hi, sorry to bother, but I wanted to know how to merge two separate libraries in Calibre.

Last month I lost one of my hard disks and I had to start a new library in Calibre, 2 weeks ago, after much searching I found that I did a back up of my library 3 years ago and I'm uploading the library now but I'll like to know how to merge them.

Thanks for any help.

Be well, Monica

First I would use Find Duplicates plugin: find Library Duplicates.

<assumes the other library can be seen by Calibre (even if on an attached flash drive)>
Once you resolve what you want to merge (to keep which is more current)

Or, when you want to resolve at a later time....
simplly set Preferences: adding books: Adding Actions (a tab): When using COPY TO LIBRARY to always CREATE A NEW RECORD for each duplicate format (this only kicks in IF the same title has the format)

While viewing the SOURCE library, select all the books you want to merge: right click Copy To Library: <target>optional action

Also, if the source library has columns that the distention library doesn't, when the requestor shows that is asking which columns you want, select which columns you want to copy over.
