How to preserve palm leaf manuscripts

Hello, I would like some advice to preserve some artifacts that I have. They are old manuscripts written on a type of palm leaf from Sr Lanka. Each manuscript has rectangular leafs. They are very brittle and cracks easily on its grains. I have scanned them but want to preserve the originals. What would be a good way to display and keep them safe while also being visible from both front and back as they are double sided? The attached image is of one leaf. Thanks
