I'd definitely suggest keeping the Aldrich & Bray pattern cutting books. Those are classics and even if you don't want to draft a pattern from scratch they can be invaluable to help you draft style alterations to a pattern that you've already fitted for your body.
I've even used one of Bray's old books that I'd bought years before and never used to make pattern adaptations for a ballroom dress a couple of years ago. It worked really well and since then I've often read them and got ideas for other dresses too.
