I used to do this with the paper encyclopedia too... Id sit on the floor surrounded by books open to a page with slips of paper, pencils and whatever else was around as markers. I'd try to keep track of where i came from so i could backtrack through my side quests.
When tabbed browsing came around it was a relief, the browser did all that for me well enough. Unsurprisingly I frequently find out how many tabs is too many for my current computer (less frequently than 20 yeas ago tho since browsers and computers are a lot better than they used to be.)
