I'm going to post this here in the pre-all because I know alot of you undergrads are really smart, and because pre-allo gets alot more traffic then allo. So I hope the mods let this thread slide cuz I need help asap, cuz in a few hours I have to turn this paper in to my PI. Okay gotto write something. In the journal I want to submit to they have "text .... study by Joe shmoe et al.^1 showed ..." also have it as ".... study by Joe Shmoe et al. showed that .....concluded.^1" MY question is does the superscript go after the et al. or at the end of the sentence? Also other journals I'm reading have the et al. and others have et al w/o the period. One more question the et al. is some times italicized and some times is not depending on the journal, which way should I do it for an american journal. Please help a brother out and try to get this dam thing done right.
