Because dictionaries are the same as books, they are tutoring books.

use 一本 to be more specific, maybe I would lend you two if I have, if you just ask 你能借我俄汉大辞典吗，我可能还会问你，你要哪一本（如果我有好几本俄汉词典）？Usually we would say 俄汉or英汉大词典 , 俄汉or英汉小词典 It is better to say: 你能借我一本俄汉大辞典吗？我想查一个词。谢谢！

本 is the measure word for books, notebook or dictionary.

It(本) is a quantifier and is usually used to describe books.
