You always need the page number right after the author info, with no comma between them. So it’s (Brown 102) or (Brown et al. 102). This is non-negotiable, like putting a stamp on an envelope. If you’re quoting the internet without page numbers, just use the author name alone—like (Smith). And if there’s no author at all, use the title in quotation marks: (“Global Warming”).
I once saw a student write a citation like this: “(Brown, p. 102)” with a comma and a “p.” Don’t do that. MLA is minimalistic—like a clean desk versus a hoarder’s garage. Just the name, a space, and the number.
