If I understand you correctly, you are saying that your reverse proxy does not serve the documents that you expect it to, but that any document requested is served by the backend.
That is because of the ProxyPass directive that passes all requests having the URL path prefix / to the backend. If you give a more specific path as the first argument to ProxyPass, only requests for URL paths starting with that prefix will be passed to the backend.
You can also specify exceptions that are to be served by the reverse proxy by adding the following line to the top of your list of ProxyPass directives:
ProxyPass /path/to/exception !

Yes. I tried and:
At this point the ip address works as reverse proxy
the DNS address works as reverse proxy
hardcoding address 192.168.0.2 works.
For some strange reason 192.168.0.1 (the local host) doesn't work (i.e. get served by the connected host). I'm looking into that one, though we really wont have much need for it, given the above
Thanks.

Replace
ProxyPass http://tswwma.lib.loc.gov/ http://192.168.0.2/
ProxyPassReverse http://tswwma.lib.loc.gov/ http://192.168.0.2/
with
ProxyPass / http://192.168.0.2/
ProxyPassReverse / http://192.168.0.2/

I read the applicable part of the doc and tried ProxyPassReverse with and without dns names and with and without the proxy section but I still can't get reverse proxy to work. When I fire up my browser I always get the local Apache server.
Here's the relevant part of my httpd.conf:
==============================
ServerName tswwma.lib.loc.gov
UseCanonicalName On
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass http://tswwma.lib.loc.gov/ http://192.168.0.2/
ProxyPassReverse http://tswwma.lib.loc.gov/ http://192.168.0.2/
=================================================
There's nothing in my error log when I use a domain name and proxy section. as abpve.
But when I omit them it actually seems to come close to executing the proxy. Then I get the following in error.log:

It seems to be attempting the reverse proxy but fails. I noticed someone else in the mail list using VirtualHost to do ProxyPassReverse. But I didn't see the doc instructing me to do it that way.
Also, I don't remember the scoreboard, which is prominent in the log, being discussed in the docs.
BTW if I didn't already mention it, this is 2.2.
Any ideas?
Thanks in advance!

ProxyPassReverse does nothing but rewrite headers going back to the client. You want ProxyPass to actually do the reverse proxying.
Re-read the docs and basic examples:
