January 10, 2020:
A number of other places on the web are devoted to Washington, D.C., baseball, past and present. Here’s are links to some of them:
“The Expansion Nats” Facebook site:

D.C. Baseball History Yesterday and Today:
and the associated Facebook page, Washington D.C. Baseball – Yesterday & Today:
https://www.facebook.com/groups/60009109815/
A Facebook site devoted to Frank “Hondo” Howard:

Suggestions for additions are welcome. Of course, the team’s official web site, washingtonnationals.com, has many useful features, including all-time leaders lists for the Expos/Nationals franchise.
(I’m posting the Facebook links, even though I am no fan of Facebook and have killed my own Facebook account. As far as I can tell, D.C. Baseball 
History has a strong connection to the Washington Baseball Historical Society. I’m not sure the society is still active as it once was. I know that Jim Hartley stopped publishing Nats News, the society’s quarterly newsletter, but the web site and Facebook page, run by Mark Hornbaker, seem to be going strong.)
