In literature, there are two key sorts of annotations: marginalia, or the notes jotted down in the margins by the reader, and additional information formally provided in expanded editions of a text, and you can find a bit of both online. Annotated Books Online is an on-line interactive archive of early modern annotated books, where researchers can share digitized documents and collaborate on translations. For insight into a single author's notes, Melville's Marginalia provides just that. For annotations with additional information, The Thoreau Reader provides context for Walden (linked previously), The Maine Woods, and other writings. Then there's the mostly annotated edition Ulysses, analysis of Joseph Conrad's Nostromo, and the thoroughly annotated US constitution (twentieth amendment linked previously). More marginalia and annotations inside. [more inside]

The Ovid Collection Outstanding site devoted to the Metamorphoses, featuring the original Latin, five different English translations, and some foreign-language translations as well. Be sure to look at the page devoted to illustrations. Speaking of illustrations, The Ovid Project reproduces the plates from one seventeenth-century and one early eighteenth-century edition. For much more Ovid, see this German metapage.
"This is like someone handing you a camera before the first-ever picture was taken. You have no idea what the light will do and it's the same light that Moses read the Ten Commandments by." Farrell Eaves was heartbroken when his digital Nikon Coolpix fell into a New Mexico pond. Now he's grateful. He fished it out and dried it as best he could, and now it's a magical camera. Read more about the metamorphosis here (frames ahoy - click on "NEW !! Mr Eaves and his Magic Camera" in the upper left). I'm just this close to dunking mine in the tub.
