OSU Extension has revamped its free online information resource. The website, which is called Ohioline, lets you read and download hundreds of detail-packed, science-backed, expert-reviewed fact sheets on farming, gardening, food and more, including sustainability. (Try “Gray Water Recycling in Ohio,” for one.) Recent improvements include enhanced search functionality, being responsive to mobile devices, and easier-than-ever printing or saving as PDF files. Browse the virtual shelves starting here. (Photo: joegolby, iStock.)
