as a starter, I'll point out some obvious books which you just can't ignore if you are new or into carnivorous plants.
The first one is "Growing Carnivorous Plants" by Barry Rice. Still actual, it covers all genuses, going from the explanation of the mechanisms, cultivation and propagation.
The second one is entitled "The Savage Garden" by Peter D'Amato. I went through it and started to read and it is extremely complete, perhaps even more than the previous mentioned book. It ranges from the terrarium/equipment coverage, fertilizer, soil recipes and even tissue culture. It is also perhaps more directed towards the general public which makes it pretty simple yet incredibly informative.
For the french guys (I'm pretty sure there's none here), I had another book which I believe was not translated in english so if you are interested, let me know. It is decent but the two books above smoke it out of the water
Happy reading !
