How Do You Organise Your Tech Library?

Having a Tech Library can be a very helpful asset in some circumstances. This was mentioned in a post a few weeks ago.

How would one structure its organisation?

That’s not explicit, so this explanation should help. This library will no doubt be within a series of folders, with varying filenames, (which of course can be changed to reflect the title of the document).

However, when this structure is published, how does one add new documents to the library, and republish the TOC or index to reflect the new document?

I’ve been doing this manually, and a DIR listing program, but that’s cumbersome. Is there a magic bullet?
