Wow! I love old books, too!
At our university library here the sewing section is not great, but the old sewing books they do have there are wonderful! From 50s and 40s!
Trnhi, I love old etiquette books and pick them up when I find them for a good price. They make me smile! One from 1952 has a chapter called "Gracious Living without Servants"! :)
