Аннотация:London was the unrivalled centre of the English print trade in sixteenth- and seventeenth-century England, with sporadic pieces of evidence revealing an extensive book trade in regional urban centres. Previous documentation of the specialist market of printed music circulating beyond the capital has tended to be focused on contexts closely connected with London. In 1657, William London, a bookseller on the Tyne Bridge in Newcastle upon Tyne, published A Catalogue of The Most Vendible Books in England, comprising over 3,000 titles that London was able to provide for customers across Northumberland, Durham, Westmorland and Cumberland. The catalogue includes a selection of contemporary printed music books along with a detailed introduction written by London that was commemorated as late as 1808 as ‘an excellent treatise [that] has never since accompanied any bookseller’s catalogue’. London places a high value on music and music-making, and the catalogue includes, among other music items, recently published music books by John Playford. This article evaluates London’s Catalogue as new evidence for the sale of printed music outside the capital in the seventeenth century, and sets it in the wider context of patterns of musical circulation during this period.
