When reading a book in the HathiTrust Digital Library, you can now enhance your reading experience by expanding the book page and entering a minimalist reading view. Click the arrow button at the top of the left sidebar to expand the reading view. In a screen reader or braille refreshable display, it is labelled as the "About this Book/Sidebar button" and will indicate whether it's expanded or collapsed.
When the arrow button is clicked, the sidebar with different ways of interacting with a book is hidden, and the footer at the bottom of the page disappears as the scrollbar moves down. The resulting view is a clean and simple interface that allows you to read your book uninterrupted. Click the arrow button again to return to the usual book display mode.
This mode can be used in conjunction with the full-screen mode, which will expand the HathiTrust book display to fill your entire screen, not just your browser. Select the ESC button on your keyboard or click the full-screen button again to escape full-screen mode.
