In 1959, the Athlone Press of the University of London sought to publish a handbook to Old Church Slavonic in its London East European Series. Grigore Nandris wrote the first part of this handbook, a grammar of the language. Later, Robert Auty published a selection of readings as the second part.
Nandris covers the writing systems (Cyrillic and Glagolitic), phonology, morphology and word formation of OCS. His approach is diachronic, as he discusses the sound changes that separate Common Slavonic from other branches of Indo-European, and he traces noun and verb inflection back to Proto-Indo-European.
