Abstract: Four new Ramanujan pairs $ \{ {a_i}\} $, $ \{ {b_j}\} $ are given along with the theorem that no such pairs exist with $ {a_1} = 1$ and $ {a_2} = s$ for any $ s \geqslant 5$. All finite Ramanujan pairs are determined and their significance in bounding the local branching degree in the search tree for such pairs is discussed. The search techniques and programs that were used are also described. The parity of the coefficients in the power series is determined in two of the new identities. Partition interpretations of the six recent identities are also given.
