Ramanujan’s first full length research paper was entitled: “On some properties of Bernoulli number”. This was published in the Journal of the Indian Mathematical Society in 1911.

In 1912 and 1913 Ramanujan communicated 4 short papers to the Journal of the Indian Mathematical Society.

During his Cambridge years, Ramanujan published 21 research papers. Of these, 5 were in collaboration with G.H. Hardy. Ramanujan also published 5 short notes in the Records of the Proceedings of the London Mathematical Society and 6 more in the Journal of the Indian Mathematical Society.

His collected papers were first published in 1927 by Cambridge University Press and reprinted in 1999 by the American Mathematical Society and the London Mathematical Society.
