I am looking for books or articles that show Philadelphia plant history maps.
Naomi, I just wanted you to know that we are closed tomorrow for MLK holiday but we'll reopen on Tuesday. Our hours are 9-5, M-F. Can you tell me what you mean by "plant history maps"? Do you mean plant distribution maps? Do you mean that you are interested in looking at plant distributions over time? Do you have a particular plant or group of plants in mind?
The more information we have about your project, the easier it will be for us to help you out. I can get back to you on this on Tuesday afternoon.
