Letters & fragments
Each inventory follows the numbering of an identified edition. “Complete” refers to that edition and document type; it does not claim to cover every surviving document by the philosopher.
The coverage labels distinguish fully indexed corpora from lists that remain partial.

Complete inventory for this editionAll eleven notes are individually indexed; numbering and anchors were checked in the source. “Fragments” here means short notes, not eleven arbitrary excerpts. Marx’s original version must be distinguished from Engels’s 1888 wording. This does not inventory all of Marx’s notebooks and fragments.
