Mostly-off-topic: "Gleam" does not mean anything that fits in those sentences. "Glean" would fit in the first sentence, although maybe you'd rather use "discern", or something more pedestrian, like "learn" or "find" or "discover". In the second sentence, both "gleam" and "glean" are nonsensical; maybe you'd like "browse"?
