I need to finish my paper, but I’m struggling with the bibliographical section.

Have you checked the guidelines? They often provide tips for that part.

Yeah, but I still find it tricky to format the bibliographical entries correctly.

Bibliographical → It is formed from "biblion" (from Greek, meaning book) and "graphia" (from Greek, meaning writing). The word "bibliographical" refers to the writing or description of books, particularly in terms of their publication and authorship.
Memory Tip
Think of 'biblion' meaning book and 'graphia' meaning writing — so bibliographical relates to the writing about books.
