Here's another hodgepodge of things you will hopefully find interesting:
Springer has an ebook sale until August 1, where you can buy all books from the archive (from between 1842-2004) for 9,99 € with a coupon code. It is valid for the whole German language area, and it actually makes these books affordable, so you might want to check out this sale. (Archaeology books are under Social Sciences.)
On a completely different note, Con or Bust still has a few memberships for WordCon in Helsinki in 2017 (as well as a lot of other memberships), available to non-white SFF folks. Con or Bust aims to help non-white SFF fans attend cons - because more diversity is a good thing.
The EU VAT is still a topic, and whatever happens now after the referendum in GB, this chapter is not over for any seller in Europe. Here's an update from the Action Group, and maybe you can help, too, and take action as they suggest. Gratuitous bonus: Brexit comic.
CityMetric has a post about small changes that make huge differences in how women move and what they use in cities - a really, really interesting read.
Finally, there's a competition about creating spiral textiles inspired by a find - you can participate and create your own interpretation using historic textile techniques. More info can be found on their website spiraltextile.com.
