Kostin or Zakozhurnikova? Russian language in the 3rd and 4th grades
M.L. Zakozhurnikova's Russian language textbooks for grades 3-4 (1959) chronologically and logically continue the line of N.A. Kostin's textbooks for grades 1-2 (1953). However, N.A. Kostin's textbooks for grades 3-4 (1949) are the "original" textbooks in this line and were simply not reprinted in 1953. In grades 3-4, you can study using either Kostin's or Zakozhurnikova's textbooks. Link to a detailed story:
