Provenance (geology) to determine the origin of sediments. This is often used in conjunction with the study of exhumation histories, interpretation of drainage networks and their evolution, and forward-modelling of paleo-earth systems. In combination, these help to characterise the "source to sink" journey of clastic sediments from hinterland to sedimentary basin. Provenance (from the French provenir, "to come from"), is the place of origin or earliest known history of something. In geology (specifically, in sedimentary petrology), the term provenance deals with the question where sediments originate from. The purpose of sedimentary provenance studies is to reconstruct and to interpret the history of
Up to Now (autobiography) relating to other prominent figures such as the British statesman Viscount Grey. Shaw's book was the first of two autobiographies published in 1929 with the title "Up to Now". The second was by the American politician and four-time Governor of New York, Al Smith. As "The Times Literary Supplement" pointed out, the title promised more to come, but although Shaw lived on for another thirty years, he never published a sequel. In the late 20th and early 21st centuries, "Up to Now" continued to be used as a source for biographical works on Gordon Craig, Isadora Duncan and Ellen Terry.
