Content Snippets from hmdb.org
"Hundreds added monthly. ...â–¼One of our correspondents has stood in front of each historical marker or monument, taken its picture, and entered its location and other information. An editor has reviewed and approved each entry. For some very few entries without photos, their location was carefully researched. No other national historical marker list can make this claim, and a number of them borrow information from us, some without permission."
"These counts are as of last night and also include war memorials."
"How many historical markers are there in the United States? We�ve found 236,669 so far. Adding more daily."
