Sher has a "Standards" Real Book...don't think "3 Views" is in that one.
The Sher Real Books Vols 1-3 do have their share of Standards, though...I would say most of the tune-age fall under, maybe, the Jazz "Classic" umbrella.
...and, no doubt, you're rubbing elbows with more schooled players than I.
(Although in my jazzy/R&B band, I am the least schooled).
Example: One of the groups I'm with is a New Country parody band...the other day, someone asked for the changes & the pedal steel guy sez "Ab to C#"...the girl on keys laughed so I said, "You meant to say Ab to Db".
Well, the steel guy sez "No such thing as "Db"...I said "C'mon".
..& it went on from there with me, basically, looking like an ass (no assist from the hottie on keys, either!).
