Biometrika tables for statisticians. Volume 2 / edited by E.S. Pearson and H.O. Hartley. (OCLC #223625397)
Despite this 1972 volume being marked as Volume 2, I was most comfortable having it on its own record in the catalog. The preface even says “We claim no more than that our Volume 2 is one of many possible companions to Volume 1.” The volume does not have its own unique title, so Volume 2 is in the 245 ǂn (number of part).
One reason for the oddness is that Volume 1 of this title had a lengthy publishing history of its own, described in our 1984 printing:
First Edition 1954 Reprinted 1956 Second edition 1958 Reprinted 1962 Third Edition 1966 Reprinted with additions 1970 Reprinted with corrections 1976 Reprinted 1984
Though we have several versions of Volume 1 in our collection (1958, 1966, 1976), the piece in hand is not specifically “part 2” of any of our volume 1’s.
