It earns a solid as a reference material. It loses a star only due to component obsolescence, which is unavoidable in printed electronics books.
However, I can help you in two ways:
Back in the golden age of analog and early digital (roughly the late 80s/early 90s), Elektor Publishing took the best projects from their monthly magazine and crammed them into a brick of a book. While the title says "305 Circuits," it feels like a thousand.
