Hey everyone, quick question – sorry if this is the wrong subreddit. If I am citing an author for the first time in the middle of a sentence eg. ‘Brown (1999) says’, do I need need to include the first name eg. ‘John Brown (1999) says, or is it not needed. I can’t find guidance for this on the Chicago Manual of Style (the style I use for citations) so if anyone can point me in the right direction that would be great!
