Found under Places -> Manage Places is a page to help in managing places across all of your data.
Consistent formatting, spelling, and punctuality in place names, and place names containing only place information, is important for many reasons:
Examples: with "Starting with":
Other checkbox options restrict the list down further to help you find different sets of places that might need to be updated.
The list of places shows the matching results, sorted by state / country, county, and city / town. Blanks in each part bubble up to the top of the list.
-- With each place name also shows the number of times each is found.
-- In cases where the place is found only once, a person icon links directly to that person's page.
-- The link appearing as a number of lines links to the full search results for that place.
-- A blue pin icon indicates that the system has stored the coordinates to identify this place on a map, and is linked to that map.
-- A red icon indicates that the system has tried to find it, but has not been successful. Thus the place may be misspelled, in an incorrect county, or somehow isn't a valid place.
-- A globe icon links to one of several sites that help you to find where the place is. Note that if a place is not found here or on other websites (links below), this is a good indication that it is in correct and needs more research.
When clicking a place, the fields at the top of the page become editable. If you should discover a place name is misspelled, or you want to change formatting or punctuation, editing it here and clicking "Save" will update all cases of that event with what you enter.
URL: Each city or town can have an associated website or URL with more information, a page that is primarily about that city or town. This is often prepopulated with a Wikipedia page. For others not defined, you can supply a webpage address. This then appears on the browse page, when clicking a place and then "More on this location".
Coordinates: Filling in the coordinates is optional. With most U.S. places, this will fill itself in when the system tries to identify the place on a Google map page. In cases where the place is not found, you can also identify it yourself by filling in latitude and longitude coordinates here. These can be found on several websites such as USGS or Global Gazeteer.
For the URL and coordinates, these are only editable if they have not previously been defined -- so you can't erase anything that someone else supplies for this place, or vice versa. If something here needs to be changed, contact the administrator.
