Something I recommend every collector have at their disposal is a Tube Substitution Guide. They are plentiful and cheap. You would be suprised at how many valid substitutions there are.

Also good to have are Receiving Tube Manuals. Personally, I use an RC-17 (1954) and an RC-30 (1960s).

The RC 17 covers the earlier tube well while the RC-30 covers all the newer stuff.
