On this page you will find a list of online resources that may be useful in researching your essays. Please note that this is far from exhaustive, however, and there are many more ebooks available on specific authors (Edgar Allan Poe, Shirley Jackson, H.P. Lovecraft, and so on) available through the library.
For the books and journals, most of the links below will take you to the Library catalogue page so you can log in and read it; some will open PDFs of the books themselves.
In addition to those listed below, and your own searches through the Library, don't forget the Internet Archive. It is a growing resource, with an amazing quantity of primary and secondary material that can be read/watched for free online (c. 25 million books, nearly 6 million films, and so on). It's worth doing some searches for keywords/authors etc. to see what they have.
The American Nightmare , dir. Adam Simon (opens in YouTube). This is an excellent documentary about American horror films from the late 60s to the 80s (including Night of the Living Dead). It discusses them in the context of US political and social history, and includes some great interviews with film makers and academics. I'd highly recommend it if you're at all interested in the subject.
Fear Itself, dir. Charlie Lyne (opens in iPlayer; may just be easier to search for it in your app). Their blurb: "Fear Itself takes viewers on a journey through fear and cinema, and asks whether horror movies know us better than we know ourselves. Encouraging viewers to interrogate a diverse range of images and sounds sampled from 100 years of cinema, Fear Itself informs and unnerves in equal measure, changing the way you watch horror movies for good."
A History of Horror with Mark Gatiss, Part 3: 'The American Scream' (opens in YouTube) The other parts, also on YouTube, are worth seeing as well, but this episode focuses on American horror cinema since Psycho. Not as good or useful as the Adam Simon documentary, but entertaining.
The University also subscribes to Kanopy, an online streaming service similar to Netflix. It has a lot of educational material as well as films. If you log-in, you can watch both The Witch, and this 30-min lecture on the Salem Witch Trials. There is also a HD version of Night of the Living Dead (better than the YouTube copy), and Jordan Peele's two great films, Get Out and Us, are available.
