I did manage to retrieve a fair chunk of older BALUG history/archives.
Thanks to The Internet Archive, I got what would seem to be much of the older mail list materials. Covering from approximately 1997-01-27 through approximately 2001-02-11. We have the list materials from 2001-06-15 going forward. The gap from 2001-02-11 through 2001-06-15 might be "lost" or very hard to obtain ... unless we find someone who saved an e-mail archive that includes that. That gap is likely from when the Internet Archive made its last pass over the older mail list locations, and when those locations were last used. On 2001-06-15 the lists picked up starting at a new location.
There's still a fair bit of other material to retrieve. Some of the quite old web stuff (which can still probably be pulled from The Internet Archive - I've gotten much of that already, but have some other pieces to retrieve) ... and there's much of the more mid-timeframe range web content (e.g. meeting minutes and materials and lots of other useful/interesting stuff) ... from roughly 2003-09 through 2007-05 ... most of that is "trapped" behind some broken PHP/MySQL on our "legacy" site, ... there may also be some stuff that may be difficult to infeasible to find towards the early end of that range - most notably from the prior site from last pass of The Internet Archive through to the last changes on that older site before it went away and was replaced with the newer site.
Anyway, I/we will likely make these older materials available (at least what we've got or been able to retrieve thus far) in the not-too-horribly-distant future. Would be nice to also close in the gaps of thus far missing or not presently accessible materials ... at least as much as feasible, anyway.
