Septology (Septologien) — beginning with The Other Name (Det andre namnet: Septologien I–II)

The true first edition is the 2019 Norwegian "Det andre namnet: Septologien I–II" (Det Norske Samlaget), with the two later Norwegian volumes "Eg er ein annan: Septologien III–V" (2020) and "Eit nytt namn: Septologien VI–VII" (2021) completing the sequence — collectors of Fosse pursue the 2019 first volume as the key book. The first English-language edition is "The Other Name: Septology I–II," translated by Damion Searls and published by Fitzcarraldo Editions (London) on 10 October 2019 in their signature blue French-flapped paperback (352 pp., print ISBN 9781910695913; 9781910695920 is the ebook) — this UK Fitzcarraldo printing precedes all other English editions and carried the work onto the 2020 International Booker longlist. The US edition (Transit Books, Oakland) followed on 7 April 2020 (336 pp., ISBN 9781945492402) using the same Searls translation, and is a later, separate issue that does not precede the Fitzcarraldo first.
