The Novgorodsko-Sofiysky Svod () is a tentative name for a hypothetical common source for the Novgorod Fourth Chronicle and the Sofia First Chronicle, according to Russian philologist Aleksey Shakhmatov.Bobrov, p. 129

Shakhmatov initially dated it by the year 1448, hence it also used to be called the 1448 compilation (), but later revised his opinion to the 1430s. Some Russian philologists shared his opinion, while others attribute the common source to the 1418 compilation of Metropolitan Photius.Bobrov, p. 131
