Lists are one of the strange byproducts of daily life. You hardly ever think about them — until, of course, one of them becomes obsessive enough to turn into a book. But even for the rest of us, a list can reveal much about the habits of its maker — the multitaskers and the romantics, the punctilious and the impulsive among us. In the hands of artists, a list can become a document of the art-making process or even a work of art unto itself. That’s the idea behind this new book by Liza Kirwin, curator of manuscripts at the Smithsonian’s Archives of American Art, which counts hundreds of thousands of lists in its collection.
