Фолклор: Леринско и костурско

Folklore: Lerin and Kostur Region by Pavlos Koufis, published in 1996, is a significant work focusing on the folklore of the Lerin (Florina) and Kostur (Kastoria) regions in the Greek part of Macedonia. The author, a teacher, aimed to promote the preservation of the cultural heritage of this area, including its language, songs, and dances.

The book's introduction places the work in a historical context related to the Greek Civil War. Koufis emphasizes the importance of the right to speak, write, and be educated in one's mother tongue and presents the book as a form of resistance against attempts to suppress this cultural identity. The content is based on various historical sources.

The book also includes a detailed section on the local Slavic language spoken in Lerin and Kostur, which locals refer to as "our Macedonian language". This section delves into the dialect's unique pronunciation and grammatical features.
