I believe the Jacobs book you refer to is The Schocken Book of Jewish Mystical Testimonies. Louis Jacobs also translated the first source text that I recommend to Freshman students of Kabbalah, The Palm Tree of Deborah. Another, more recent, excellent annotated translation of this is by Moshe Miller. All three of these may now be found here :

In regards to
@HoldAll 's advice regarding Gershom Scholem, I absolutely agree. For better or worse, however, as I was cutting my teeth on Kabbalah, after learning the basics via Hermetic Qabalah, he was pretty much all there was at the time. Now I would recommend the bibliographies in his books more than the books themselves.
I do suggest four Academic alternatives : Daniel Abrams, Moshe Idel, the aforementioned J.H. Chajes, and Isaiah Tishby
Tishby authored the most erudite, readable, and exhaustive work on the Zohar available to date. You may find it here :

As in everything else, one must follow one's innate spiritual compass in regards to branches of a particular subject. Be it in C/Q/Kabbalah or Wicca vs Traditional Witchcraft or theistic vs non-theistic Satanism - to name but a few examples - it is always best to taste types A, B, and O to determine which best nourishes one's soul (or lack thereof).
