Bartleby provides reference books, fiction books, and nonfiction books for free. You can browse the famous illustrations in Grey’s Anatomy, or learn about proper grammar in Strunk’s Elements of Style. This is a great way to access thousands of well-known and reliable resources quickly and easily. Since the information is all online, you can easily search the text for specific parts.
This amazing anatomy tool is a 3D model of the human body. The website says it best: “You can peel back anatomical layers, zoom in, click to identify anatomy, or search for muscles, organs, bones and more. You can also share the exact scene you are viewing by copying and pasting the URL.” Unfortunately, you can’t view it in Safari—you need either Google’s Chrome browser, or the latest Firefox beta version (both of these are available for download at the link).
