The work provides a complete description of the phonetic, morphological, word formation, accent, and lexical features of the dialects spoken in all 26 villages of the former Samokov district. It contains 12 maps outlining the areas connecting the dialect with other western dialects and dialects in Vardar Macedonia. The abundant material included in the work has been collected personally over many years from 164 informants, a list of whom is attached. The detailed study of the dialect of each village makes it possible to supplement some of the data from the Bulgarian Dialect Atlas. The same informants also collected and prepared for publication the author of the "Dictionary of the Samokov Dialect," which includes 9,000 dialect lexemes. Once published, the dialect will be presented in its entirety. The Samokov dialect is of interest to specialists in Bulgarian studies, Slavic studies, language history, ethnography, and folklore, both in Bulgaria and abroad.
