I also think they're booklice. The beetle is hard to tell from the photo but resembles plaster beetles e.g. Adistemia or Dienerella

They are miniscule, they look like booklice but I am not shure. On the 4th photograph shows a beetle, but I cant figure out if this one is a treath to our collection our building or not. Ass always your help will be most appreciated.
