If you're a numbers person (as in somebody who easily remembers numbers, lucky you) and a textile archaeology nerd in addition to that, the two numbers in the blog title might ring a bell for you.
If not, let me bring you up to speed: York Archaeological Trust has been publishing a lot of very nice, very helpful shiny books about various aspects and find groups of all the digs done there - and York has a lot of history, and has had a lot of digs, and consequently there's oodles to research, and to tell. York also boasts a number of textile finds and textile tool finds, which is a delightful thing.
To make all this good stuff even better, they've decided, once they run out of the printed copies of their books,
to make them freely available as pdf online. I've posted about this at least once before, but that was a good while ago. Back then, I had downloaded those of interest to me, though the really, really yummy ones - about textile production and textile finds - were still available in print and thus not as pdfs.
Just recently, though, I searched for something else, and the engine threw me a link to one of these two books on the YAT website. Off I went - and to my great delight, both
17/5 Textile, Raw Fibre and Cordage from Coppergate 16-22 and
17/11 Textile Production at 16-22 Coppergate are available now. (Direct links to the pdfs - but do go and
visit their page listing the rest of the volumes of Archaeology of York, there's many more.)
