Are these old pamphlets worth anything?

I have two pamphlets that were passed down to me from my grandparents and I was wondering if they are worth anything.

1 The first one is titled, " in time of EMERGENCY..... A Citizen's handbook on.... nuclear attack....natural disasters"

It was published in March of 1968 by the department of defense.

2 This one is titled, " Reader's Digest.... First Aid Guide... 1966 Revised Edition"

It was edited by Lois Mattox Miller

These are both original copies, and are in decent condition.
