ELI5: Why do so many books have blank pages at the beginning and/or end?
gpt
It's the result of the way books are printed. They aren't printed as individual pages. They will make small booklets of, say, 16 pages each, by printing one big sheet, folding it and cutting it, then those booklets are bound together. More often than not, the number of pages of text isn't a perfect multiple, so there will be some blank pages.
