Thank you very much for the fast delivery of my books. They were exactly in the condition you described and one of the volumes contained a very interesting dinner invitation and menu. Thank you very much, as well, for cost-effectively sending parcel via normal US Post.
Many thanks for your prompt reply informing me that the book is now set aside for the library. It's great that you are willing and able to send an invoice with the book -- it makes life a little easier when you work for a very large institution! Thanks again.
