That seems to work for you but you know what pam would do as a former librarian Pam wants to do that to my LPS but I won’t let her as I have them in types of music like rock roil oldies Motown country and so on. I know the songs who signs them and the cover of the LP. That works for me just like what you are doing because it works for you. Stick to the things that suits tour life style good for you. .
One is never a FORMER librarian, however, I group my reference books by subject. I don’t buy fiction books. I let my local library do that for me.
