Oxford libraries have very strong collections of Church Slavonic manuscripts and early printed books. There are two standard bibliographies of Church Slavonic manuscript collections in the UK which can be used for locating these. Printed finding aids are still the best way of searching for Church Slavonic materials.

As a result of the Oxford Google Project (2004-2009) many 19th century books from the Libraries' collections were digitized including secondary literature on Church Slavonic language and texts. Here are a few examples of some digitized versions of secondary literature including some by the important 19th century Slavonic scholars Vatroslav Jagic (1838-1923) and Josef Dobrowsky (1753-1829).
