Couldn't the plates only be read with special glasses or sight or something? And weren't they gold or something?
I don't know really, just some vague things I was told, but maybe distorted or not understood fully. I do know the library I work in has a couple of Mormon books (lots of books about Mormons in general though I'm not sure why... some guy donated them all...) in some weird looking written language... and I'd heard to understand the language you needed some sort of special glasses or sight that were only granted to the guy that recorded it once. The language almost looked like a written Native American language, but it wasn't. We've got lots of those books too.
*Edit* Found what the alphabet is called, the Deseret alphabet:

There's also a link to the Cherokee alphabet page, which is the Native American language that my supervisor said it looked a lot like when we first came across the book.
And this is the book that we have:
The Book of Mormon : an account written by the hand of Mormon, upon plates taken from the plates of Nephi
Smith, Joseph, 1805-1844, tr.
Publication info: New York : Pub. for the Deseret University by Russell Brothers, 1869.
Physical descrip: [8], 116 p. ; 23 cm.
General Note: Title and text printed in the Deseret alphabet. cf. Bancroft, Hist. of Utah, 1889. 712-714.
I'm pretty sure that's the right holding for the right book; it's the only one I could pull up in our library with the Deseret alphabet. I know that's the cover of the book I saw.
