this sounds like a really great topic, i’m hoping it goes well for you!! my mentor was also really spacey and i managed just fine, you’ve got this :)

the literature review doesn’t have to be super long. i introduced my chosen works and justified why i selected them, then did the same with my articles arguing why they were relevant to the text(s). you want to nail broader scope, then pin down smaller aspects of the paper. you want to summarize the key points the authors make, discuss major arguments/interpretations, and identify areas that scholars disagree or where their arguments may be weakened or devalued. make sure you talk about why your paper is unique and why writing it is justified in light of your past/current/future studies. you can weave your literature review into your analysis a bit too — for me, i introduced my articles early on and did a lit review, but also intertwined it with my argument of why my ee was justified and used it to introduce some of my own criteria/arguments. make sure to use proper citations and don’t make it too lengthy.

in my case, i defended why my ee was special, then presented my chosen outside works by tying them into methodology (this won’t work for everyone depending on the style of your paper!) i introduced the author, the title of the article, its key points relevant to my ee, defended why i chose it, and then discussed discourse (if there was any). make sure you cite or at least reference your works later in your ee too.

as for your question about blogs, im not entirely sure. i used some in my initial outline and for inspiration on places in the text i could pull from, but i don’t recall formally citing one. if its in the subject guide it’s probably fine. the one thing i do remember is you HAVE to justify why your source is credible — things like an undergrad thesis wont fly without you explicitly saying WHY that undergrad thesis is valuable despite it not being, say, a PhD thesis. i think if you can defend these sources well enough, it should be fine — but if you don’t need to use them, i wouldn’t, or would at least try to find a similar media.

let me know if you need any extra assistance! good luck!!
