Online Help was a popular topic in the latter part of the 1990s. At least for developers, as you can see from the cover below of Visual Developer. The Jan 1998 issue featured:

  • HTML Help: Win98′s Engine Transplant, Jim Mischel
  • WinHelp Extension Tabs, Andrew Brundell,
  • Critque-Help Magician Pro 95, v4.0, Jim Mischel
  • Critique-HelpBreeze 2.0, Gary Warren King

and a round-up of available WinHelp Tools and Utilities, shown in the images below of the Visual Showcase.
