Leon rubbed a hand on the back of his neck, looking embarrassed. "Well, kinda... It might be futile." He stood with a sigh, returning his eyes to the shelves but hardly taking anything in at this point. "I was just hoping to find some basic reference material on the composition of minerals here on earth. I think I'm familiar with some of them, but..."

There were metals on Expel that didn't exist on earth, and vice versa most likely. Many were basically the same, however. Iron was a good example. If he had that, he could work with it as a base, but most of the metal here was a mix of other basic metals. Perhaps he should be searching more for books on the composition of metal piping?

He sighed again. "I don't think I'm going to find what I'm looking for here."
