I find I am carrying in my vehicle various field guides and speciatly reference books, mostly hardcover, but a few paperbacks. I use them to review plant and fungi species I am trying to identify, plus a few other things. Occasionally I remove the books to a nearby outdoor site for perusal.

How best to protect these 30 or so volumes, weighing in total about 20 pounds or so, in transit and out-of-doors, from dust and water, while keeping them relatively handy to get to?

Thoughts?

Thanks.
