Having an Archivist come across an ancient dwarven library...

[atemu1234]

...full of divine spells, of course. What spells would be in there for him to write down?

[Flickerdart]

Silverbeard. Thousands and thousands of scrolls of nothing but Silverbeard.

[QuickLyRaiNbow]

Create water, light, mending.

Bless water, magic weapon, shield of faith

Align weapon, gentle repose, make whole, shatter, spiritual weapon (warhammer), status

Continual flame, daylight, glyph of warding, locate object, magic circle against chaos, meld into stone, stone shape

Discern lies, greater magic weapon, repel vermin

Hallow, disrupting weapon, dispel chaos, righteous might, wall of stone

Those are the core Clr spells I'd consider up through level 5. It depends on what your campaign world is like, though. And also what the power level of your archivist is.

As general principles, I'd want: light generation, object destruction and repair, buffs to lawful things, protections against chaotic things. If your campaign has an Underdark of sorts, and the dwarves do Underdarky stuff, then mental protections and anti-vermin stuff too.

All the Scrolls of Create Water? They're Create Beer.

[Duke of Urrel]

Quite a few cleric spell scrolls that you find in this library may be domain spells in domains favored by dwarves: Creation, Earth, Good, Law, and Protection.

The best spells may be protected by Glyphs of Warding, of course.
