In my continuing search for apartment-friendly organizing solutions, I’ve found a sturdy product from 3M that can help renters from having to put nails into the wall.
Picture Hanging Strips (12 pack) are like heavy-duty velcro. You adhere one strip to the wall and one strip to the back of whatever it is you wish to hang. When it’s time to move, pull the release strip and cleanly remove the adhesive from the wall:

3M also makes Poster Strips (48 strips), which are very similar to other adhesives already on the market.
