”Open Roots” makes an old book attractive and accessible again. This project is intended as a contribution to sustainability and and open education. “Root Development of Vegetable Crops” was first published in the United States in 1927 and is in the public domain by now. For their academic work, two scientists planted various crops on specially prepared fields. They later lavishly excavated them and illustrated the root growth. ”Open Roots” reworks the book into a website in order to make it available to many people. During the design process, special attention was paid to readability, interaction and orientation. The website features customized solutions for a better reading experience on a screen. In order to make the data more accessible, tables with test readings were turned into interactive infographics and the static illustrations were digitized and animated.
