Hello Frisby - thanks for raising queries about the locations of the playbills. It is a good question and I'm a little surprised that there haven't been more questions about it! One of the main reasons for launching this project is to capture more individual item-level details - information from each playbill sheet. The existing catalogue records describe what is held at volume or 'collection level' only - just one brief record covers a bunch of playbill sheets collated together into individual volumes. The British Library has acquired its great range of playbills from two sources: by purchase of individual sheets and collections of sheets from the book trade by past curators, and from donations or purchases of collections from known collectors, such as those collected by Sir Augustus Harris, manager at Covent Garden Theatre Royal Drury Lane; William Archer, the theatre critic; Sidney Carr Glynn; and William Barclay Squire. The main sequence of playbills (shelfmarked 'Playbills 1-482') comprise a range of periods, theatres and locations, some were already arranged by theatre or location but others - from miscellaneous locations and theatres - have been sorted into rough alphabetical groups in volumes. Researchers looking to use the playbills for their research have been supplied with a reference handlist which lists volumes by locations - this reference aid has generally only been available to readers in the Rare Books Reading Room (it hasn't been published). So, whilst we do have some form of guide for access to playbills by location it isn't exactly 'out there'. We think it would be great to have locations matched to individual playbills for the 'miscellaneous' regional volumes (there are about 40 venues in all), but the task would be best assisted with an automated list of known locations. I hope this is something that can be done in future. Meantime, I can email you a copy of the 'Register of Playbills' with locations / shelfmarks. Must be remembered that not all of the playbills volumes have been digitised, but it will help you find out what locations are covered in the collection.
