The journal Papers of the Institute for Bulgarian Language Prof. Lyubomir Andreychin includes scientific works focused on the study of Bulgarian (modern state and history of Bulgarian, Old Bulgarian, dialectology, relations between Bulgarian and other languages, theoretical and methodological linguistic research) that, because of their extended nature, cannot be published in full length in scientific journals while not reaching the volume of a full-scale monograph. Only original research is considered for publication, i.e., one that has not been previously published (neither in printed or electronic editions). Submitted manuscripts are reviewed by two anonymous reviewers.
