NYPL has a wealth of travel resources from various times in history. Use these headings to identify some of those, which might mention places of interest in the course of their guide information or their narrative accounts of travels:
[place name] Guidebooks
[place name] Description and travel
These headings are for other particular types of resources that might help you confirm the existence of a place or the use of a place name, though their main purpose is not to give location:

[place name] Geography
[place name] Administrative and Political Divisions
Villages [place name]
Cities and towns [place name]
