The remaining 1880s publications on chanties, that I know of, are:

1883: Luce - I think most of the chanties are taken from Adams 1879
1887: Davis and Tozer
1888: L.A. Smith

Right now I want to mention Davis and Tozer. The vagarious editions (each quite different) are hard to come by. Once Lighter put up the table of contents for the first edition. Here it is:

1. Sally Brown
2. Away for Rio
3. We're All Bound to Go
4. The Wide Missouri
5. Leave Her, Johnnie ###
6. Can't You Dance a Polka? ###
7. The Black Ball Line
8. Hoodah Day ###
9. Homeward Bound
10. Whiskey for My Johnnie
11. Reuben Ranzo
12. Blow Boys, Blow
13. Blow the Man Down
14. Tom's Gone to Ilo ###
15. Hanging Johnnie ###
16. Haul Away Jo'
17. Haul the Bowlin'
18. Paddy Doyle's Boots
19. A-Roving
20. Storm Along
21. Mobile Bay
22. Salt Horse
23. The Dead Horse
24. Eight Bells

I won't have access to this edition (unless I fly to Dublin), but I am going to get a later edition and assume that the earlier shanties were unchanged. For now, I thought I'd take note of which of these songs had appeared in literature already up to this point. I don't mean the same lyrical versions, I just mean if the song had been mentioned at all.

So, all the chanties have turned up in some form (A-Roving not as a chanty). The songs with ### after them, however, have a significantly different or original phrasing.

In all, the book appears to be quite original (despite the common songs, they look like they'd be original versions). What intrigues me more is the possibility that many of these forms set the mold for future interpretations.
