I’ve kept meaning to link to this, the TV Tropes Wiki. It’s not just for TV, but also film, animation, videogames, etc. Basically, it’s a compendium of techniques, conventions, plot devices, structures, and anything else that can be catalogued about how media tell stories. And as a wiki, you can add your own examples and ideas throughout! It might be helpful for you as you look for examples & ideas for your final papers.

Warning: might suck up hours of your life, so surf cautiously…
