Billingsley P. Ergodic theory and information

Wiley, 1965. — 207 p.
This book originated in a lively series of lectures which Professor Billingsley gave to one of the London Mathematical Society's Instructional Conferences, lectures which we felt should be made available to a wider public. It is particularly fitting that this book should initiate the new Series, because the Tracts and the London Mathematical Society's Conferences are both intended to make new mathematical developments generally accessible while the pulse of life still beats in them, and before they have acquired a chilling permanence.
