Marxists Internet Archive — Marx’s outgoing and jointly authored letters in the four chronological correspondence indexes (consulted 2026-10-26)
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.
Complete inventory for this edition · 548 indexed entries548 distinct letters by Marx or jointly authored with him, listed in the four consulted chronological indexes; every included link was checked. Two index errors were excluded: the 1835 school essay and a military article by Engels. Identifiers reproduce source paths, not MEGA numbers. Dates are not reconstructed from filenames. This inventory is complete for this verified digital selection, not for all letters preserved in MEGA or for incoming correspondence.
