In his book The Card Expert Entertains, Fitzkee categorizes card tricks in nineteen fundamental effects. They are:
2. Disappearance (Four Ace Assembly, Cards Across)
3. Transposition (travel) (Card to pocket, wallet etc)
4. Transformation (Diminishing Cards)
6. Restoration (torn and restored)
7. Animation (Haunted Deck)
8. Overcoming laws of gravity (Rising Card)
9. Attraction (Magnetic Cards)
10. Sympathetic (Triple Coincidence, Do As I Do)
12. Denying natural physical laws (change shape)
13. Spectator failure
14. Control (Remote Control)
15. Identification (90% of all tricks?)
16. Thought reading (performer reads thoughts)
17. Thought transmission (performer projects thoughts)
18. Prediction (Brain Wave deck)
19. ESP (sixth sense)
As Fitzkee points out, tricks are often a combination of the fundamental nineteen effects. Tricks are different tricks only from the viewpoint of the spectators and not the performer, no matter what number of accessories and methods are used.
Mr. Giobbi expands on Fitzkee's fundamental nineteen effects and distinguishes the difference between themes, effects, and tricks.
I haven't compared Mr. Giobbi's list to Fitzkee's, but I'm sure they all fit into the nineteen basic effects, maybe even more than once.
