Most of the compositions of G W Crawford are written on a large scale and the collection consists chiefly of full scores, piano reductions and orchestral parts. There are very few drafts or sketches: almost all the compositions are in their final form, and many are in the hands of copyists. Most of the works are undated. Those dates that appear (usually on the last page or leaf) range from 1892 to 1941, but it is rarely clear whether these are of composition, revision or performance. Almost all are unpublished, including those composed pseudonymously. A few of his early compositions have opus numbers.
