August Strindberg's letters were compiled by Kerstin Dahlb├Ąck. They include all published and unpublished letters available on 1 August 1991. The material should be considered a working material, as it has not yet been satisfactorily proof-read. Additionally, the letters from the last years have preliminary designations and need to be renumbered in accordance with parts XVII-XX of the published letters of August Strindberg.
