Emily left me a comment. (Thanks, Emily!) She got a reply from the Brooklyn Museum of Art about the Knitting Lace book. Here's what it says:
Fans of Knitting Lace Publication:
We appreciate your interest in the future republication of our catalog Knitting Lace. We are now working on the necessary steps to be taken to grant permission for a reprint of the catalog.
We will keep you informed as we move forward.
Thank you for expressing your interest.

Woo-hoo! Looks like we made them wake up and pay attention. Thanks to everyone for contacting the museum to help make this happen. I'll post when I hear who is the lucky publisher who will be reprinting the book.
