Realistically, this work is much more of historical interest than of 
current technical reference value, so durability isn't that much of 
a concern either way. If the cost between hardcover and softcover is 
minimal, the softcover is overpriced and it's a moot point. Just go 
with hardcover and call it good.

Whatever works.
