I have a wizard who obtained a spell book containing a couple of spells one spell level higher than he can normally cast.
With a scroll, the wizard could attempt to cast it from the scroll (by making an arcana check)... it would then disappear from the scroll. How would this work with a spell book? Presumably, a spell in general doesn't disappear when casting from a spell book (ritual casting, for example).
If the wizard had an appropriate level spell slot (because of multi-classing), could they use it to attempt to cast the spell from the spell book (losing the spell slot if they failed the arcana check)?
You can’t read another wizard’s spellbook. With great care, time, and money, you can translate and copy the spells into your own spellbook, but you cannot cast spells from someone else’s spellbook, period.
Spell scrolls are designed to be cast by anyone whose spell list includes the spell. Spellbooks are designed to be legible only to the individual wizards whom they belong to.
A scroll essentially contains all of the magical essence needed to cast a spell, so the user just needs to "complete" the casting.
A spellbook contains the formulas and equations to prepare those spells. Essentially, your next step is to spend time transcribing those new spells into your own spellbook, and once you are of a level high enough to prepare them, you can do so and cast them normally.
However, it is also possible to write a scroll into your spellbook (which consumes the scroll, without casting), so if you happened to find a collection of spell scrolls, that would be like finding a spellbook that you could cast from... once.

That makes sense.
