I have a couple of shelves contained by my room that contain nice sports autographs but the shelves are kind of unlit and it's hard to see. Are here little battery powered lights than I can stick inside these shelves to brighten them up?

Answers:    Target have battery powered LED puck lights by two companies that work economically for this purpose. One is by RiteLite and the other is by Ontel. You can even swivel and angle them to better position the light. They use three AAA battery in respectively light, and you gain only almost 60 hours of light up to that time you need to replace the battery. LEDs last comparatively forever, you a moment ago gotta keep feed them batteries.
What color?
There are mobile lights you can get but they will cost a fortune within batteries to save lit. If the shelves are in the sunlight contained by the day time, you can find solar power lights that will recharge themselves in the daytime and stay lit most of the darkness.
