This book was written by a librarian at the New York Metropolitan Library. She collaborated with artists on projects wherein she would find books on whatever they were interested in -- 19th century children's book, typography, maps, bookplate, decorative bindings, etc.--and they would create projects inspired by the books.
The reason this book is cool is because she lists the Library of Congress subject headings for each topic, plus she provides the names of specialized digital collections.
