[3.5] Ways to learn spells from a different class list

[Story]

Of course, the argument's largely irrelevant, since Extra Spell was errata'd to specifically not let you get other spells.

There is Limited Wish which can duplicate any spell level 5th or lower, (Wish does 6th or lower, but is 9th as opposed to 7th so it's less effective in this usage).

Yeah but they have those awful XP components. Miracle on the other hand is amazing. Probably the best spell in the game apart from Shapechange.
