Last year, the New York Academy of Medicine made the dreams of coloring nerds everywhere come true with #ColorOurCollections, a five-day event where cultural institutions made images from their archives available in the form of coloring book pages. Suddenly, you could add your own color palette to art from the Smithsonian or other museum collections.

This year, the event is back, and there are 67 coloring books from which to choose. They are pulled from artistic and historic collections from across the world—from university libraries to public institutions like the Washington State Library to organizations like JSTOR. Each institution has posted a PDF of its unique coloring book at ColorOurCollections.org, which is ready to be printed out and made vibrant. Among the images you can color are root vegetables featured in the Denver Botanic Garden’s library, pictures of famous women in history from the New York Academy of Medicine, and illustrations from Alice’s Adventures in Wonderland from Philadelphia’s Rosenbach Museum.

Once you finish your artistic interpretations of the museums’ collections, share your work on Twitter using the hashtag so that it can be admired by librarians—and art lovers—around the world. The event runs until February 10, but you’re free to keep coloring all year long.
