#4: Keep paths open
Unless your library is already scheduled for renovation, you probably can’t realistically move all your shelving to create wider aisles, but have you inadvertently created choke points as a result of where you’ve set up furniture or display units? Make sure passages through these areas are wide enough for someone in a wheelchair or with a walker to comfortably navigate. As a way to test this, try pushing one of your larger book carts through the space with the long side of the cart parallel to you. If you can pass through with a cart, someone with an electric wheelchair can probably pass through too.
