I know this is a strange question - but how do you manage library books coming too quickly?

I like to use my library for most of my book needs. I can use their app for ebooks sure, but I prefer physical ones to a degree (like 60/40 split). My biggest problem is I can end up with more books than I want at once, I generally read 1-3 books a month and for example, I have 4 library books right now.

I don’t want to be rude and hold a book from someone else who wants it - so my question is, how do you organise your library requests/orders so they aren’t all coming at once, but you can still enjoy/savour them?
