The Society of Professors of Slovakia was a very important association of teachers in the first half of the 20th century (during the existence of the 1st Czechoslovak Republic). Through its almanac it helped in searching the national identity of Slovak teachers, especially secondary school teachers. Apart from reinforcing patriotism the Almanac of the Society of Professors of Slovakia made a significant contribution to raising the quality standards of teacher education by issuing various articles. The largest role in shaping the Almanac being a professional journal was played by its editors. The paper deals with the textual analysis of the Almanac of the Society of Professors of Slovakia in the period of 1928-33, during which it was published under the leadership of the editor-in-chief Pavol Florek. Based on the written communication of the editor with contributors the paper describes Pavol Florek´s efforts to improve the professional quality of the journal. In this regard a significant contribution was made by Jan Kvacala, a founder of modern Comeniology in Slovakia. The last part of the paper provides a selection of the correspondence between Pavol Florek and Jan Kvacala in the form of commented letters, preserved in the manuscripts owned by Jan Kvacala.
