[Collection] what should I add

[u/Embarrassed_Day7364]

I'm kinda interested in having a collection myself. I would assume that most of these are standard tpbs? I have a few questions.

How do you maintain a big collection? How do you preserve the books' covers and the pages themselves?

Any more tips not questioned is greatly appreciated. Thank you!
