Wehausen and Laitone 1960
J.V. Wehausen and E.V. Laitone, Surface Waves in Fluid Dynamics III in Handbuch der Physik 9, chapter 3, pp. 446-778, ed. S. Flugge and C. Truesdell, Springer Verlag, 1960.
An amazing paper devoted to an almost complete description of linear water wave theory as it was known in 1960. It is almost embarrassing how little more has been added to the subject.
The paper is available online.
