Items that allow spontaneous casters to prepare spells?

[NobodysHome]

OK, I admit it, I'm lazy.

In my home-brew campaign I gave the sorcerer an item that allowed him to prepare a handful of spells a day from spellbooks. Someone helpfully pointed me to an existing Pathfinder item that does just that. (I'd made up the item to throw him a bone after the bard got a nymph's blessing and the paladin inherited a 72,000 gp sword.)

Problem is, I can't find it, and given the choice of searching 1000+ of my posts for clues or being lazy, I'll just post here. (I'll be honest. I've spend around 90 minutes searching, so I did do due diligence.)

QUESTION 1: What items (if any) allow sorcerers to cast prepared spells?

QUESTION 2: Ditto for Oracles.

Thanks!

1. There isn't such an item. What your helpful someone was probably pointing to was the Ring of Spell Knowledge, which can gain a spell by being exposed to a written or cast form of the spell in question. The liberal interpretation of the ring suggest that you can take a single spell from a spell book and put it in the ring making it usable by the sorcerer.

2. See above, only the options are more limited since clerics don't use spell books.

There's also a feat in the Pathfinder Society Primer which gives you some prepping ability for both classes. That's about it.

Mnemonic Vestments allow a spontaneous caster to cast a spell from a scroll once per day (using her CL, spell slot, and not consuming the scroll)

Ring of Spell Knowledge and Page of Spell Knowledge are ways to add to your spells known.

The Versatile Spontaneity feat allows a spontaneous caster to prepare a spell she doesn't know but is on her spell list.

There's the Oracle of lore revelation Arcane Archivist that lets you cast a wizard spell from a spellbook using your slot (but it erases the spell).

Aha! It was the mnemonic vestment that I was looking for!

Beautiful! Thank you!

I had no idea it worked for oracles. Since it does, I'm all set!

(My GM has the bizarre requirement that I be of the correct race or society to take racial/societal feats, so Versatile Spontaneity won't work as I'm not a Pathfinder.)
