Maybe what I need is abook for houses, a bok for transits and a book for aspects. I saw a couple well rated on amazon.es.
Houses:
The Houses - Temples in the Sky bh Deborah Houlding - short but excellent run down of house meanings from early to modern times.
Houses of the Horoscope by Alan Oken - modern view longer than Houlding but not as useful overall because Houlding is much easier to find what you're looking for.
The House Book by Stephanie Camilleri. This lists each planet in each house. Again a modern account, so it includes the outer planets and it's not too bad in mis-assigning activities to houses.
The Twelve Houses by Howard Sasportas. This was written in the mid 1980s and shows only a dim awareness that perhaps the Astrological Alphabet approach to the Houses is wrong. This is excusable in that the traditional revival had not really got underway but really is now a rather dangerous text to use to learn about the houses. It's also the fattest tome and therefore the more expensive of the four.
I would suggest starting with Houlding and if you decide on a modern approach then Camilleri as your second. If you get into esoteric Astrology, then add Oken.
Aspects
Logically you need to know about these before you can tackle transits. Aspects are now given more emphasis because many, if not most of the traditional techniques for linking planets have been lost and are now being slowly recovered. Aspects were always important but they were placed in an 'astrological toolbox' that is now reduced considerably.
Aspects in Astrology by the late Sue Tomkins. This became the 'bible' of the modern approach to aspects and if you follow the psychological approach you really need it sooner or later.
The Sun & The Aspects by Maurice McCann. This is an excellent book on the theory of aspects combining the traditional with the modern. It discusses issues like orbs, planets other relationships to each other and a lot more in a slim volume crammed full of useful information. This was published twelve years ago but since then doubt has been cast on Ptolemy's role as an Astrologer (though he remains a pre-eminent Astronomer) and it's even been questioned whether his view of the triplicities and terms was ever used in practice till the late medieval times.
Harmonics in Astrology by John Addey. Since Kepler's attempts in the Seventeenth Century to 'rationalise' Astrology emphasis has been placed more on the angles between planets than on the qualities of their sign placements, which in turn has generated a host of 'new aspects' starting with Kepler's conversion of being inconjunct or aversion into the quincux and semi-sextile and adding in sem-squares and quintiles for good measure. Addey takes this several stages further by diving the circle by successive numbers to create 'harmonics'. This is still a very fashionable theory.
Traditional Astrologer did not write books on aspects, they had more important things to discuss LOL , aspects were only the classic majors and these were covered sufficiently to use them in any introductory work on Astrology. Wiliam Lilly considers them in less than a page./ The imporant thing with aspects was do they help or hinder the planet that is being considered. Usually Trines and Sextiles to benefics help, Squares and Oppositions to malefics hinder. The way in which help or hindrance comes about can be taken from the natural (and accidental) signification of the planets involved.
Transits
For the modern Astrologer, transits are often the starting point for prediction and, when I learned, the approach tended to be Transits for Mars or Jupiter outwards and Secondary Progressions for the inner planets, and most especially the Moon.
Traditional Astrology always saw Transits as the last thing to look at, having used other techniques to identify important time periods in someone's life. Transits then narrowed this down to days or even hours, rather than weeks or months. Most of the 'higher' techniques have largely been lost, though Solar Returns are becoming more widely used and Primary Directions (and for that matter other directions) are being used. So you might need to buy a book that looks at more than one predictive method.
Planets in Transit by Rob Hand. The classic text for modern Astrologers but largely rejected by its author, who now propounds a traditional approach. A large volume giving virtually every conceivable transit. This doesn't look at anything else but transits.
Secondary Progressions by Nancy Hastings. Again another 'bible' of the psychological approach
The Art of Predictive Astrology by Carol Rushman. Combines progressions and transits in the way that I mentioned in the introduction to this section.
Again, because of their position at the bottom of the list of predictive techniques, traditional authors didn't really write books on Transits. Even Jean Baptiste Morin, who did write such a book as part of his Astrologica Gallica, put it at the end of the sequence, having discussed primary directions and solar returns first. It doesn't make any sense to read this book on a stand alone basis. So simply see Transits as triggering events that are already foreshadowed by more long term analysis. They are unlikely to have any effect at all, unless they indicate things have shown up in a more 'advanced' technique. Modern Astrology might have difficulties explaining why a transit has no effect (often by claiming that the effect was an inner one, rather than something that happened in the external world). Traditional Astrology says that some transits may pass us by without any effect at all. As the tradition is concerned with the outside world, both of these approaches could be 'true' in this respect.
