Absolutely.
I reference the 5e DMG and the 1e DMG a lot. The 1e DMG I have on PDF with bookmarks which makes it much easier to get to sections I am trying to find than flipping through either in hardcopy. I remember in the 80s having read the 1e DMG enough to sort of remember where some things were when flipping around but it was often not quick or easy.
The 5e one is not the easiest to find stuff either. I can find specific magic items fairly easily because it is an alphabetically organized subsection of the book that covers a bunch of pages, but most other topics take a bunch to find where you are and where you want to go from there when flipping around.
I found the 4e rulebooks' superior and clean layout made finding stuff easier.
