Thanks for the podcast but oooo it is long, I don't really want to listen to it. This paper sucks dude. I haven't written papers of this size before and I don't feel like I know the topic very well. I feel the same way you do.
Can you ask a librarian for help? At my school, you can sign up for an appointment with a librarian, even a librarian who specializes in the field that your topic is in, to help with your research. We also have a place for help with writing and, to a lesser extent, research. It helps a lot more if you go in with specific questions that will give your essay direction when they are answered.
Google Scholar, public library databases, university databases. Some databases are more specialized, like social studies. When in doubt, there's probably a filter for more relevant articles, articles that are referenced the most. Think of different keywords you can look up. My teacher recommended looking at specific authors, like if I find a good paper I should consider looking at other work from those authors. I think she recommended that because my topic doesn't have that much research in it, especially in English :).
Looking at a lot of scholarly work might be difficult to get through. If you have a specialist you can go to, good, idk but maybe instead of reading everything by yourself it would be more efficient to scan it for passages that are probably useful and ask to go through it with them. I'm guessing that when you find a paper you often won't have to read the whole thing so look through, keeping in mind questions that will specifically apply to your paper. I used mostly books, definitely only reading a little.
You know the drill: just write. Fuck order, clarity, fuck everything :), if you immediately think of a correction that is fine. I struggle with this a lot. You might create separate documents or spaces for different topics.
When you say it's daunting, are you talking about the length of the paper, potential amount of research you will have to do, other?
There must be some kind of tricks you can do to put the length of the paper out of your mind, like shrinking the window so you can't see the white space that you still have to fill in, or once you have a page of writing, you never have to see white space again.
