Mark Wilson's Complete Course in Magic
Mark Wilson
Cards, coins, rope, mentalism, and stage magic in one 500-page volume.
The broadest single starting point in print. If you have enjoyed dipping between categories here rather than specialising, this is the natural next step — it teaches a bit of everything with clear illustrations, and it is the book most often handed to a curious beginner.
In print and widely stocked by general booksellers and magic shops. Common in public libraries.
