1 For a description of the Helsinki University Library in general and the Slavic Department in particular, see the articles of Maria Widnas, “La Constitution du fonds slave de la Bibliotheque de Helsinki,” Cahiers du monde russe et soviitique, II, No. 3 (1961), 395-408, and of Charles, Timberlake, “The Slavic Department of the Helsinki University Library,” Slavic Review , XXV, No. 3 (Sept. 1966), 513–22Google Scholar, as well as my comment on Timberlake's article in Slavic Review, XXVI, No. 2 (June 1967), 351. A slender, thirty-six-page monograph by Gronroos, Henrik and Myllyniemi, Kaija, Helsinki University Library : A Short Survey (2nd rev. ed.; Helsinki, 1965)Google Scholar, includes a brief historical sketch of the library, a general description of the various collections, a brief bibliography, and several photographs of the library's interior

2 The omission of Chteniia v Obshchestve liubitelei russkoi slovesnosti v pamiat’ A. S. Pushkina pri Imperatorshom Kazanskorn universitete (Kazan, 1900-1904) was probably a clerical error.

5 The compiling and editing of information of all Cyrillic entries in the Helsinki University Library was done by Maria Widnas, and the Union List was compiled under the supervision of a special committee headed by Jorma Vallinkoski, chief librarian. Similar union lists were published in science and technology (1950-53), law (1956), the social sciences (1960), and medicine (i960). Although Timberlake (p. 518) cited the exact titles for the first two, he did not mention the other two, of which Yhteisluettelo Suomen tieteellisissä kirjastoissa olevista uikomaisista yhteiskuntatieteellisistä aikakauslehdistä (Union List of Foreign Journals of Social Sciences in the Research Libraries of Finland), published in Helsinki in 1960, would be of special interest. Scholars interested in additional European locations of Russian périodicals should consult two major lists that are frequently overlooked : Périodiques slaves en caractères cyrilliques : État des collections en 1950 (2 vols.; Paris, 1956) and Peter Bruhn, Gesamtverzeichnis russischer und sowjetischer Periodika und Serienwerke (Wiesbaden, 1962-).
