If you are working from a reading-list and if you have a reference the first step is to go to Databases A-Z and select a bibliographical database. The following databases have material relevant to Russian and Slavonic language and literature. Most of the articles indexed in these databases will be in English and other European languages.
Articles in English for journals published in North America are thoroughly indexed in ABSEES. Articles in English for journals published in North America and Western Europe including the UK can be found in the MLA. MLA also indexes some Russian journals.
Note: you can only find journal articles in these databases. You will NOT find journal articles in the online library catalogue (unless you do a Journal articles search on SOLO!)
There is also one printed source that is still very useful (although not up-to-date):
Terry, Garth M. East European languages and literatures: a subject and name index to articles in English-language journals, festschriften, conference proceedings and collected papers Oxford: Clio Press; Nottingham: Astra Press, c1978- (=Z2487.E5.1979.T3=R)
