Inscription is the skill for making spellbooks. You need a minimum 80 (I think) skill to attempt a spellbook.
A very important stat to go with inscribe is mana regen or meditation. You use mana when you make a scroll or book so you have to wait to regain it to attempt another.
There aren't any other skills that go with inscribe. If you work the skill to GM level (100) you get a 10% damage bonus an all the spells you cast,
