Though unknown to most readers, no one made a greater contribution to reading habits in America than Ray Trautman. Growing up in the rural Midwest, Trautman looked to reading as a way of exploring the world and yet, discovered that with no community library and limited funds finding books was a challenge. This sparked in him a lifelong passion to build libraries and ensure free access to books for all. After working his way through college, Trautman became an independent bookseller, and then joined the Civilian Conservation Corps during the Depression, building libraries and teaching people how to read. In late 1940, after earning a degree in library studies from Columbia, he landed the job of a lifetime: Chief Librarian of the Army. Many military leaders believed books were an unnecessary distraction for troops, but Trautman relentlessly championed books, believing that they were key to the fight against totalitarianism and ultimately built the largest and most far-reaching library system in the world. He devised the "Armed Services Editions," wallet-sized paperbacks and printed miniature magazines for soldiers. He also created the most popular comic book in the Army, Overseas Comics. Along the way, Trautman fought book bans and book-resistant generals, was nearly killed in the Battle of the Bulge while on a special assignment for Dwight Eisenhower, and joined forces with librarians and publishers to spread access to reading. Trautman was credited with distributing nearly a half billion books, magazines, and comic books to troops. When the war ended in 1945, Trautman brought the fight for books home: advocating for rural libraries, building libraries in prisons, campaigning for more books for the visually impaired, and working to develop materials for adults with low reading proficiency so they could improve their literacy skills. A Librarian's War introduces a man who dedicated his life to instilling a passion for reading and unhindered access to books.
