I remember a while back reading a book about the different forms of time travel in movies and science fiction. I can't seem to recall the name now!

3Was it one of Paul J. Nahin's book on Time Machines and Time Travel? – user14111 Mar 7 '15 at 5:23

Here's the Library O' Congress catalogue stuff:
Nahin, Paul J. Time Machines: time travel in physics, metaphysics, and science fiction (2nd ed). NYC: Springer-Verlag (1998). ISBN 0-387-98571-9.
Throughout the book are hundreds of examples of time travel in various media of Sci-Fi. Similar premises and stories are compared and examined with various prevailing and even a few of the more fringe viewpoints; all with a rigorous mathematical framework but not overbearingly so on the reader.
On the whole, the subtitle says it all: it examines both the physics, the metaphysics, and the cultural phenomenon that is time travel.
It is also probably a decent enough reference for anyone who wants to tackle some of the unanswered story-identifcationtime-travel questions here.

1A newer book by this author, perhaps a re-titled new edition of the one mentioned here, is Time Machine Tales. – Ubik Apr 25 '17 at 22:07
