A recent (July 29, 2014) article on the website of the College of Arms in London speaks of pedigree rolls and a project to locate, rehouse and list comprehensively the large collection of rolled material held at the College, of which pedigree rolls comprise the largest portion.
As a part of this project to preserve and conserve these materials, the newly-appointed Pigott Library at the College has been fitted out with archival shelving and environmental controls, and the rolls housed in custom-made acid-free boxes. Over 1,100 rolls have now been entered into a searchable database there.
There’s more to the article of course, but I’m not going to repeat it all here for you. Feel free to go to the website of the College of Arms, or click this link http://www.college-of-arms.gov.uk/news-grants/news/item/100-pedigree-rolls to not only see what the College is doing with this project, but to see some of the pictures that they have included of some of these one-of-a-kind pedigree rolls. (I especially like how the reverse side of one roll was used to draw out some chess problems!)
The College of Arms is to be congratulated on this massive undertaking, which will preserve and make more accessible these unique materials.
