tldr; you tend to remember a) things that interest you and b) things that you repeat. I am also very fond of reading but I usually read fictional books. One of the things that I have noticed is how I tend to remember the plot even after a long time. For instance a few days back I was reading a Sherlock Holmes story (the speckled band) after about a decade and I was surprised at how well I remembered the solution to the puzzle. Incidentally I have also noticed this on previous occasions like when I turned the pages of count of Monte cristo or the three musketeers or other books that I enjoyed back in the day and I instantly found myself "in the world" when I expected to be "out of place". On the other hand I tried reading a Shakespeare play that I had the opportunity to read before in my high school and I didn't remember it quite as well. No wonder there because I never enjoyed his work even though I tried many times. So my conclusion is that I tend to remember things that I like. Even if I forget them I get up to speed very quickly. But the problem is there are things that are good for us that we might not enjoy. I don't particularly enjoy reading non fictional books but I know it is important that I read them if I want to learn. So I read them slowly making progress each day. Often taking handwritten notes and re reading things that I found interesting the first time around. I have this theory that if you read anything some parts stick in your brain and they stay with you forever. Even if you feel like you have learned nothing you always take something with you. It could be a changed outlook on the subject or maybe a better understanding but you never leave empty handed if you read. I have no evidence to support what I have said though it's just something that I have noticed in my self :)
