This info is getting added to the individual spell pages. In the question of whether spell X stacks with spell Y, the answer is always yes. You just have to read the spell carefully to see whether it's increasing or setting values. If there are any exceptions (and I don't know of any) they should just be added as notes to the individual pages themselves.

In the question of whether spell X stacks with itself, this should also just be on the spell's page.
