Aside from the Tanakh, Talmud, Shulchan Aruch, Mishne Torah and the likes..... Is reading normal books about practical laws in Judaism considered "Torah Study"? I mean books like "To Be a Jew" for example. It deals with several aspect of every day Jewish life from Blessings, to Kashering, to going to Synagogue, explaining how to slaughter the animal, how to behave, modesty, etc.
Mishna B'rura 554:5 says one may not issue halachic rulings or hear a court case on 9 Av (when Torah study is forbidden) "because law is Torah". The same would seem to me to apply to practical-halacha books of te sort you mention, but, as always, consult your rabbi if this is a practical question for you.
