Halloween is here again, and with it comes a perfect excuse to pull out some of the creepiest stories and images ever captured on film. For generations, ghost photos have fascinated believers and skeptics alike—sparking chills, debates, and plenty of late-night storytelling. Whether staged, misunderstood, or something truly unexplainable, these pictures have earned their place as some of the most talked-about snapshots in paranormal history.

It’s National Library Week in the US, and we’re honoring the occasion by bringing you ghost stories from haunted libraries all around the world! Much like the iconic library scene in the movie Ghostbusters, these literary atheneums are stacked with creepy ghosts, shadow figures, and paranormal activity. Not only do we love tales of the paranormal, we also think circulation of some library appreciation is long overdue, so please check out these 7 haunted libraries around the world before we reference another bad library pun!
