We have another new display up on the first floor featuring books and DVDs on unexplained phenomenon, legendary creatures, alien abduction, and haunted locations. This was my favorite section of the library to browse as a kid, and you can find most of the books on these topics right at the beginning of Nonfiction at Dewey numbers 001 or 130.
You can also search the library catalog, using subject keyword terms like Parapsychology, Unidentified Flying Objects, or Haunted. You'll get the most results from the Contains... search option. You can narrow your results to just DVDs or Adult Nonfiction from here as well (unless you're looking for children's materials, then try j Nonfiction). Click on the image below to enlarge.
