British University Observatories and the Wider World, 1919– 1939

The fact of the matter was that at such observatories as Yerkes, Lick and Mount Wilson a new era started around 1900 that small observatories could not hope to emulate. Their re-entry into observational work near the frontiers of astronomical science would have to await the world-wide co-operative projects that did not come until the 1960s.
