I have 1,000 books in Calibre which I would like to manage better.
Last time it got to 1,000 I removed half of them I saved them in an Archive folder on my pc.
That worked quite well for a while as less to browse. However after a time I found sometimes I was downloading the same books again.
As read a lot and couldn't remember the titles. lol.
Any suggestions of another solution would be great.

What do you do?
