These 37 research publications of Ramanujan are reprinted in the Collected Papers of Srinivasa Ramanujan, edited by G.H. Hardy, P.V. Seshu Aiyar and B.M. Wilson and published first by the Cambridge University Press (1927) and later by Chelsea (1962). The questions posed and the answers provided by Ramanujan, 59 in all, in the Journal of the Indian Mathematical Society follow the research papers in the Collected Papers. Besides the Preface, the editors include two biographical Notices, one by P.V. Seshu Aiyar and R. Ramachandra Rao and another by G.H. Hardy, at the beginning of the Collected Papers. Notes on the research publications and some extracts from Ramanujan’s letters to G.H. Hardy are in two Appendices, at the end of the Collected Papers. Appendix B Wren Library Card Catalogue and Papers of Ramanujan With the help of Professor Robert A. Rankin, the Wren Library has catalogued the papers of Ramanujan. These have the reference addresses as Add.Ms.a.94, with a superscript which refers to the specific document, and as Add.Ms.b.100–107C. The papers that are available with reference Add.Ms.a.941−18 are contained in a large sized (A3-size) 2 inches high cardboard box. The reference Add.Ms.b. 100– 107C refers to the five bound volumes (foolscap size), and, in addition to these, the papers and letters are preserved in two large (A3) sized thick cardboard boxes. In this Appendix are given the details of the Card Catalogue on Ramanujan, as well as the details of the Ramanujan MSS as maintained in the Archives of the Wren Library of Trinity College, Cambridge University. In fact, a part of the Appendix Card Catalogue is what is contained in Supplement II of Venkatachaliengar’s article, as “A list of all the Ramanujan - material at the Trinity College Cambridge given to Professor C.T. Rajagopal by Rankin”. The Card Catalogue in the Wren Library of Trinity College: 1. AIYAR A(P Venkatesvara Seshu) see AYYAR (P Venkatesvara Seshu) 2. ANDERSON (Sir Hugh Kerr) see HARDY (G.H.) 3.
