Case Library
Two shelves. Theirs first: an index of free cases from clubs and firms, listed and linked, never hosted here. Ours: 15 original cases, run with Richard and scored.
A public index of the free cases that consulting clubs and firms publish for practice, catalogued here and read at the source.
490 entries, live now: 478 individual cases listed one by one, and 12 case books and published sets still listed at book level, the ones whose individual case titles could not be verified from the book itself. Between them the entries represent 569 cases.

Counting follows the index’s rules: a case printed in two books is counted once, and book level counts are the labeled figures on their cards. Every entry names its source and links out to it. The cases belong to the clubs and firms named on each card. This site is not affiliated with them, and their names appear only to identify the source.
The count on this page is the count of live entries, computed from the index data itself. It grows as books are indexed case by case and as member contributions clear review. We will not print a bigger number than the index holds.
Every case on this shelf carries the same parts:
