That's a good point I should have mentioned earlier; as Etene notes, there are increasingly more subtle and complex "correspondence overlays" that complicate trying to go up the learning curve, since they are often intermingled rather carelessly in modern interpretation. These run all the way from the "psychological overlay" that was grafted on as the New Age evolved in lock-step with populist Jungian psychology, up to the increasingly rarified ponderings of esoteric systems like qabalism, ceremonial magic, astrology, "occult" number theory, color symbolism, various mythologies, etc. Think of it as climbing a very tall ladder; each layer of corrrespondences is a rung, and they go on upward until the air gets a little thin.
It might be best to start with learning material that came to us from the "pre-New Age" era. As much as I think The Pictorial Key to the Tarot is top-heavy with pomposity and many of Waite's divinational meanings seem wackily out of sync with the images on the cards, it's probably one of the first books you should pick up just to be able to perform "sanity checks" on more modern tarot writing (let's just say anyone with the dedication and the means to self-publish can become a published author these days - I'm not being dismissive here, just factual). It's also fairly light on annoying "psychobabble" (just heavy on Victorian stuffiness).
