This paper presents an account of the editorial work performed so far on the volumes of The Correspondence of Jakub Deml published in the editorial series launched in 2010 by the Dauphin Publishing House. Over a period of five years (2007–2011) a student seminar at the Faculty of Arts, Charles University in Prague systematically collected unpublished letters written by Czech poet Jakub Deml and prepared their editions. The students’ work (especially by Šárka Kořínková and Iva Mrázková, and other editors) became the foundation for the editorial series which aims at issuing more comprehensive collections of the poet’s letters. Having summarised the first four volumes already published (containing letters to and from the priests Josef Ševčík, Matěj Fencl, Evermod Vladimír Balcárek and the artist František Bílek), the paper gives an overview of specific features of Deml’s epistolography including a great number and variety of addressees and styles, a great dispersion and number of manuscripts (running into the thousands), variants of the same letter (with later copies and printed versions). The paper also outlines some dilemmas faced by the editors involving significant references between Deml’s letters and poetic works, relations between the letters and external events, questions about graphical features of the letters and about editorial principles regarding language and orthography. The paper concludes with an outline of objectives for future research and possible next editions.
