Why was Windows 3.0 WinHelp called an online help system when it ran offline?

Some time ago, I described Windows 3.0’s WinHelp as “a program for browsing online help files.” But Windows 3.0 predated the Internet, and these help files were available even if the computer was not connected to any other network. How can it be “online”?

The term “online” originally meant “immediately available on a computer”. For example, if you are working on a system with hierarchical storage, the “online” files are the ones that are accessible right now, and the “offline” files are the ones that have been archived to tape and will take some time to retrieve and make online.

The term “online help” refers to the fact that the help files are readily available on your computer. You don’t have to go dig through your shelves looking for a manual.

Back in the day, a computer that was accessible via a network or some other remote connection was generally called “up” rather than “online”. Officially, “up” referred to whether the computer was running at all, but since these types of computers (mainframes or timesharing systems) had as their sole purpose to be connected to by other computers, being “up” was useless if they weren’t also open to connections.

It does mean that we have the somewhat paradoxical terminology that online help is available offline.

But it’s not really a paradox because the terms “online” and “offline” are referring to different things. In the phrase “online help”, it’s referring to the help. The help files are online (readily accessible via computer). But “available offline” is referring to your computer (can connect to other computers).

Your computer is offline (relative to other computers). The help is online (relative to your computer).

Bonus chatter: Of course, now that many systems have migrated the help files themselves to Web sites, you now have online help that is not available when offline.
