Good morning collective wisdom,

I'd like to get an idea of how other institutions store their map materials. Specifically:


1.       According to best practices, what is the maximum number of items (ex: sheet maps or encapsulated aerial photos) per folder?

2.       Do you find that you store more or less in each folder than what's best practice? If so, what is that number?

3.       Does the number of items per folder vary based on whether they're stored in lateral flat file cabinets or vertical cabinets (like these: https://ulrichplanfiling.com/shop/planfile-2-blueprint-cabinet/).

4.       About how many folders do you store per flat file drawer and/or vertical cabinet?

Thanks so much for your help!
