So many files, so few files.

An ordinary data base, where each datum is, instead of a single file, a list of the file and all of its previous versions, which are identified by appending the file's original date into its name. (you'd rename today's yesterday's version either with its original date, if you can remember it, or today's date, since the new one won't have a date in its name - that would be the "superseded" date - as part of the "update" script. Yeah, today's date would be easiest.)

e.g:

A: Amplifiers 1. Transistor a. common emitter i. Circuit-A Circuit-A.20050618 Circuit-A.20041303 b. Circuit-B Circuit-B.20050213 2. Tube ... B: Oscillator ...

and so on.

Figuring out categories, of course, is left as an exercise for the reader. ;-)

Good Luck! Rich

You could use a standard revision control system to handle this. E.g. like svn, cvs, bitkeeper. Periodically (every month say), use something like wget to synchronize your copy with the remote site, then use the revision control tool to save the snapshot. You will then be able to take your copy of the site backwards and forwards in time. The revision control tool only stores the *changes* to the files, so you do not need space for N copies of the site.

Of course this is still quite a big job, especially for multiple sites! You could use scripting to automate a lot of it. I imagine the main problem would be "dynamic" sites that use javascript, or get you to fill out a form, in order to access data.

Don't know... some specialised version of the above, perhaps.

Not only that -- kepp in mind that websites are less and less just pseudo-static html files but often have javascript and other (often dysfunctional) "goodies" in them: this is where automated website mirroring tools hopelessly get lost.
