Are you talking quilts or clothing?
I may have missed it but I look in the library too. Plenty of quilting and sewing books with patterns in them. If it's clothing the newer books are still in style.
Quilt patterns never go out of style. They just become vintage.
I also look for older quilting books in thrift stores and go through the patterns there. Every now and again you can find a few vintage gems.
They're also one more thing I keep my eyes open for at estate sales.
