The illustrations include a wide variety of images, including portraits, scenes from stories and scientific diagrams. Even decorated letters and the fancy little curlicues printers placed between sections of text make it onto the Mechanical Curator's Tumblr. Each illustration comes with information on what book it's from, but nothing else. The Tumblr posts do include a link to order the book from which each post is culled, either to see it in the library reading room, or to get it as a PDF. But not all of the books are available to order digitally, leaving those of us not in the U.K. to puzzle fruitlessly over tufted-eared dragons and weirdly seductive cherubs.
