I don't belong to the safety police but... I have never read any detailed information on how some of the different safety mechanisms work-for example on a bolt action. The Remington locked trigger movement-as I understand it while other systems lock the bolt. What do they mean by bolt? Do they mean the firing pin? In any event are there any books explaining the different systems?

Locked bolt, means the Action itself cannot be manipulated, opened, or otherwise without disengaging the safety.
Remingtons made prior to 1983 (I think that is the right year) locked the bolt handle down when on safe. This prevented the bolt from accidentally opening as you walked. It required you to move the safety to the "FIRE" position to open the action and unload a chambered round.
Newer Remingtons no longer lock the bolt when on "SAFE". This allows you to unload while the safety is still in the "SAFE" position.
Many other guns use a 3 position safety which allows you to lock the bolt down when all the way back. The middle position allows you to open the bolt, but locks the trigger. All the way forward is to fire the gun.

It basically comes down to "there's more than one way to skin a cat"!
99% of fire trains have 4 parts in one form or another.
Trigger,
Sear,
Firing pin (or striker),
Bolt (Or other breech closure device).
Blocking any of the parts in the firing chain should , in theory prevent firing, so depending on the individual designs different parts of the train can be immobilized to make a "Safety".
Some lock things directly, others indirectly by blocking another part that would interact with the essential component, some also do double duty, immobilizing the bolt as well.
Some block the trigger (Garand, M1a), some block the sear (FAL), others block the striker/firing pin & bolt (Lee Enfield) others lock the striker (Mauser) & so on. This is way over-simplified but gives an idea of the options out there. One of those multiple firearms assembly/dis assembly guides should give you lots of research material as they usually have exploded diagrams of the actions of a bunch of different types.
