Of all the wonderful things a great library can be, “a vessel for preserving the natural world,” may not be the first thing that comes to mind. But the library can be a preservational space as significant as a national park or a wildlife preserve. Not just in words and images, but in actual specimens. Take, for example, the copy of a rare and unusual book by Elizabeth Allom, The Sea-Weed Collector, found at IU’s Lilly Library.
