Hey /lit/ I'm making valuable annotations on pic-related, I did not want to rape my softcover so I'm using a lead pen-pencil instead of a pen.
Will the annotations (they are written in a compact manner) become faded and unreadable in decades, should I be using a pen instead?
In decades? Probably, just buy another cheap copy or take annotations on a notebook or transfer them to your computer. I still have some old notes from like... Ten years ago, and what I wrote is still visible, but it certainly faded a bit.
