Personalitycafe forums also have pretty much the whole chapters in each type sub-section. Usually stickied. The actual book is worth it though.

Have you read The Wisdom of Enneagram and Character and Neurosis? Those are some of the introductory books to cover if you're learning enneagram. If you have read these books, which aspects of 5 vs. 1 seem confusing?

Integration/disintegration points offer a good clue to your type. 1s integrate to 7 and disintegrate to 4, but they don't have any access to type 8. In fact 1s and 8s often find themselves at odds not understanding each other's motives and behavior. While 5s will disintegrate to 7 but integrate to 8, so there is a stronger connection between 5 and 8: 5s look up to 8s as leaders which is not the case for 1s. For disintegration, to put it short, if you become emotional and mopey during your disintegration then this is likely 1->4 transition; for 5 is you feel like you lose your mental focus and become scattered jumping one thing to the next, this is a 5->7 move. Since 5s and 1s have such different patterns for integration and disintegration, it becomes easy to tell them apart.
