Universal Short Title Catalogue
The USTC has now absorbed all our data for the period 1601-1650, so that we provide full coverage of the first two centuries of print in all our searches and analysis. We have added an extra one million copies, with, as far as possible, call numbers. We now have located copies from 8,500 libraries, archives and museums.
The USTC now comprises 740,000 editions with 4,000,000 surviving copies. Additional data to be added over the next weeks will take this total to 780,000 editions. The USTC now includes descriptions of some 40,000 single-sheet items, and this too will climb rapidly as we incorporate several thousand further items that we have discovered in our searches in archives.
Each search now comes with a list of literature references. Where there is a record in other major on-line bibliographies, you should be able to click straight through to it. We have added one new facet, so all searches can now be analysed for printer/publishers, as well as place, language and format. For each of these searches we offer far more than the ‘top ten’ of the old USTC.
