As soon as Thomas Jefferson learned to read, he found his passion: books, books, and more books! Before, during, and after the American Revolution, Jefferson collected thousands of books on hundreds of subjects. In fact, his massive collection eventually helped rebuild the Library of Congress now the largest library in the world. Barb Rosenstock’s rhythmic words and John O'Brien’s whimsical illustrations capture Jefferson’s passion for the written word as well as little-known details about book collecting. Author and artist worked closely with experts to create the first picture book on Jefferson’s love of reading, writing, and books. An author’s note, bibliography, and source notes for quotations are also included.
