I fully agree! But, as somebody else said, it can be difficult to read old literature, as mathematical notation and terms are things that have evolved significantly in the last centuries.

There are two "new" references about "old" physics literature I particularly enjoyed: - "The Book Nobody Read: Chasing the Revolutions of Nicolaus Copernicus," by O. Gingerich, about Copernicus' book "De revolutionibus."

- "A Student’s Guide Through the Great Physics Texts," by K. Kuehn (4 volumes). It presents many original papers by Newton, Galileo, Maxwell, etc., together with study questions and exercises.
