Forgive the intrusion, but after being pointed at #32, I was thinking back to other tools I used in the MS-DOS days that might be related. After a quick search around the repo I can't see any mention of Folio Views. I have memories of using it for help with Novell NetWare in the early 1990s.
Possibly worth including?
Thanks! I found a screenshot. The file format was "Folio Infobase format" with extension
The line between ebook formats (digital document formats not primarily created for printing such as word processing and DTP formats) and hypertext formats is not sharp, so this category (including online help formats #31) is worth to explore. I'd include ebook and similar formats until the mid 1990s if they at least provide non-hierarchic in-document hyperlinks.
