SPIRIT OF RAMANUJA N xv Hardy sent the first notebook to the University of Madras where Ramanujan's other notebooks and papers were being preserved. Plans were undertaken to publish Ramanujan's collected papers and, possi- bly, his notebooks and other manuscripts. Handwritten copies of the notebooks were sent to Hardy along with other manuscripts and pa- pers in 1923, but the papers were never returned to the University of Madras. It transpired that Ramanujan's Collected Papers [192] were published in 1927, but his notebooks and other manuscripts were not published. Sometime in the late 1920s, G. N. Watson and B. M. Wilson began the task of editing Ramanujan's notebooks. The second note- book, being a revised, enlarged edition of the first, was their primary focus. Wilson was assigned Chapters 2-14, and Watson was to exam- ine Chapters 15-21. Wilson devoted his efforts to this task until 1935, when he died from an infection at the early age of 38. Watson wrote over 30 papers inspired by the notebooks before his interest evidently waned in the late 1930s. Thus, the project was never completed. It was not until 1957 that the notebooks were made available to the public when the Tata Institute of Fundamental Research in Bombay published a photocopy edition [193], but no editing was un- dertaken. The first notebook was published in volume 1, and volume 2 comprises the second and third notebooks. The present author un- dertook the task of editing Ramanujan's notebooks in 1977. With the help of several mathematicians, the author completed his work with the publication of his fifth volume [38] on the notebooks in 1998. In the spring of 1976, George Andrews of Pennsylvania State University visited Trinity College, Cambridge, to examine the papers left by Watson. Among Watson's papers, he found a manuscript containing 138 pages in the handwriting of Ramanujan. In view of the fame of Ramanujan's notebooks [193], it was natural for Andrews to call this newly found manuscript "Ramanujan's lost notebook." How did this manuscript reach Trinity College? Watson died in 1965 at the age of 79. Shortly thereafter, on sep- arate occasions, J. M. Whittaker and R. A. Rankin visited Mrs. Wat- son. Whittaker was a son of E. T. Whittaker, who coauthored with
