Provenance on the object, or an account of it in written materials from the same era, an object of study in archaeology or cultural anthropology may have an early provenance – a known history that predates modern research – then a provenience from its modern finding, and finally a continued provenance relating to its handling and storage or display after the modern acquisition. Evidence of provenance in the more general sense can be of importance in archaeology. Fakes are not unknown, and finds are sometimes removed from the context in which they were found without documentation, reducing their value to science.
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.
