"The Vanishing Hitchhiker"by Jan Harald Brunvand
Urban legends are, of course, a huge thing at this point, not only people that still believe them, but also people that know that they are not true and still appreciate them for what they are. The internet in general and snopes.com in particular has lead the way in spreading the UL word (though TV hasn't been far behind), but waaaay back in the early '80s UL's got an early shot of publicity in the form of this book, and yes indeed I was reading it.
Urban legends are creepy, that's their attraction, the idea that our normal, brightly lit, day-to-day life could easily take a turn into a turn into the dark and dangerous. That girl you offered a ride home to may just "live" in a cemetery … your night babysitting could end up with a psycho-killer hiding upstairs. Even the less outright horrific ULs tend to be unpleasant, your fried chicken could end up being a fried rat … that cookie / cake recipe you asked for may end up costing you hundreds of dollars … and every time you hurt yourself those paramedics are just going to laugh and laugh. That said, most ULs also tend to be morality tales. If something REALLY bad happens to a person, chances are they were doing something wrong which brought it upon themselves. If they aren't straight up morality tales they are usually at the very least cautionary tales. If you are going to look for a deal on your winter coat this year, do be careful, those countries where the "less expensive" ones are manufactured are just teaming with deadly snakes you know!
Now, there are two ways to explore the dark recesses of urban legends and one way is more popular than the others. You can simply tell a bunch of stories that everyone knows isn't true. People love this way of doing it as it's basically sitting around a campfire telling creepy stories, this of course is the more popular way of dealing with ULs. The other way is how this book (and how Snopes) handles them, and in my opinion is much more interesting. Instead of simply telling a creepy story, Brunvand really gets into the history of the legend, looking for where it stared, looking at different versions of the story and discussing the societal reasons for the legend. This, however, causes a problem for readers who are simply looking for a collection of creepy stories to tell their friends the next time they are on a long drive through the dark mountains. The fact that this book was written by a college professor means that there will be some lengthy and deep discussions about these legends (and page after page of footnotes, which you will not want to skip as they are quite interesting as well).
The urban legend audience has expanded quite a bit since 1981, and much like anything else that grows from a small cult audience into the harsh glare of the mainstream a lot of the newly found fans aren't going to be into all the details the way the original fans were and as such this book isn't viewed quite as highly as it once was. But don't let the dumbing down of the audience tarnish the reputation of this book. This book is what got me interested in urban legends and it's why I can spot them as easily as I can. UL's aren't just "creepy stories", they are creepy stories that try to change your mind about something, they use fear to shape your opinions on people, society and the world around you, but if all you do is read a collection of scary stories that some people believe are true, you will never realise that. This book (and the others by this author) can change that, as long as you are willing to put up with all the "boring" parts.
