Re: Building drawings from 1902


John – I have always learned that maps and other such documents should be stored the way they have been stored for years (or the way you received the document). For example, if you have a map that has been rolled for 15 years you should keep it stored that way. If you do this instead of flattening the document, it will avoid any unnecessary cracks and deterioration as it becomes brittle overtime. Same goes the opposite way. Hope that helps!
