Personally I find I sometimes get lost in the archive
(via the web interface)
though as a filename often doesn't obviously correspond to a document title.
The file naming has evolved over the 7+ years. In general, anything new is being
added with <manual part number> <title> <date>
This started on a system with 32 character file names, so <title> was ruthlessly
truncated, and as you noticed, <title> wasn't always the document title.
The worst problem with the current arrangement is file renaming and rearrangement
of the heirarchy. I'm not sure if the mirrors reflect these rearrangements.
In general though, it seems to serve it's purpose, so I'm not inclined to spend
a lot of time adding database functionality to it.
I've been working on a MUCH harder problem on how to organize the CHM digital
holdings,
of which the bitsavers archive is a fairly tiny part.
