This paper describes the development of an idiom-annotated corpus of Russian. The corpus is compiled from freely available resources online and contains texts of different genres. The idiom extraction, annotation procedure, and a pilot experiment using the new corpus are outlined in the paper. Considering the scarcity of publicly available Russian annotated corpora, the corpus is a much-needed resource that can be utilized for literary and linguistic studies, pedagogy as well as for various Natural Language Processing tasks
