I hate the "may be too late" feeling when it comes to making a musical contact; there's an old-guard #plectrumbanjo player who has had arrangements and instructional materials for sale in the past, but their domain seems to have lapsed and searching for contact info mostly turns up "has anyone been able to get hold of him" posts for the last year or two. He's in his 80s now, so nobody would fault him for putting the online hustle aside, but in purely selfish terms I would like to have gotten hold of his extensive collection of arrangements.
...although the more I read and learn, the reason that there aren't more published collections of chord melodies is that anyone who puts in the work to learn the fundamentals (which includes being able to sight-read lead sheets, and having the fingerboard and corresponding chords memorized) you probably don't need banjo-specific notation.
In general it's a different discipline and approach than folk banjo styles, and that difference is probably what I've been hung up on.
I'm reminded of the frustrating 2-3 weeks between 13-year old me getting my first electric guitar for Christmas and taking my first lesson from my stoner rock dude teacher who did house calls; my dad took me to Kurlan Music Center (RIP) and we asked for a recommendation for a beginning guitar book and the chucklehead behind the counter sold us a copy of Frederick Noad's "Solo Guitar Playing" which I'm sure is a fine resource for learning classical guitar with the help of a teacher, but a terrible book to give a kid who just wants to learn how to play like Ace Frehley
