Ever wonder why LaTeX doesn't provide a way for printing the title and author once `\maketitle` has been issued? I did. So I asked a question on the TeX StackExchange and received an interesting answer. Turns out it's an artifact of the times when memory was in extremely short supply. According to Frank Mittelbach:

The main reason was "main-memory" back in those days. LaTeX was effectively eating up half of the available space just through macro definitions. So with complicated pages or with some picture environments etc you could hit the limit. So freeing up any bit was essential and you still see traces of this in the code.

Dark times!
