Librarians, in case you hadn’t heard, are essential members of society — likely to expand minds wherever they go — and, as such, are fully worthy of hero worship (whether they’re among the coolest librarians alive or just pretty cool). That’s at least part of the impetus behind My Daguerreotype Librarian, “[a] tumblr dedicated to literally or figuratively hunky and babely librarians from the past.” Inspired by the website, here’s a little extra literary goodness: 25 awesome vintage photos of librarians from ages past, either shown or linked below.
