I really like this idea for an office or a library. Convert an old globe into a pendant light! Seems easy enough. Buy a lamp kit at your local hardware store, take apart a globe and drill a larger hole for the light. Put remainder of light together.

For a space-saving lamp, hang a lightbulb on a cord off of a wall-mounted shelf bracket. note: this isn't just any old cord and socket or any old bulb. The bracket is carefully chosen too.
