The term Pocketbook, the series to which this piece belongs, came into use in the 1600’s. Originally it was a small fold-able item that snapped shut and was thought of as a safe way to carry and possibly conceal bills and coins. It was carried in ones pocket or purse. Over time Pocketbook became synonym of purse.
Transforming books into “pocketbooks” emphasizes how priceless books and education are.
