I've tried to make a go of Calibre off and on for many years now, and have finally decided to go all in for good.

The problem is I have many different Calibre libraries scattered over different machines (running different OSes and where Calibre is no longer installed and who knows what the version was anyways) and in different cloud storage etc.

What is the best way to bring all of my disparate libraries together? This is several hundred books in my "test" libraries, so I'd prefer not to import the raw epub files and lose all my tags and so on if there is an easy way around it. Also, I have different fields in different libraries (e.g. one might have a "read" column, another might have a number of pages column etc)

Finally, I'd like to access this central library from multiple computers. I know not to have multiple Calibre instances running at the same time to preserve database integrity, but was wondering if there is a best practices solution for this. In the past I remember being messed up by one cloud provider adding "(1)" to the end of file names, as an example of why I am careful about this.

Thanks!
