Славянский именослов или собрание славянских личных имен
[The Slavonic Name Book, or a Collection of Slavonic Personal Names]

Moroshkin, Mikhail, Saint Petersburg: n.p., 1867.

A dictionary of the roots of Slavic names. Provides a large number of spelling variants and diminutives (not all of which are Russian). Entries which do not resemble Russian forms should be treated with caution as this book is plagued with errors.
