Credo Reference is pleased to announce its National Library Week Brainteaser Challenge with free access to Credo Unlimited. This weeklong celebration of 2010 National Library Week (April 11-17) will culminate with a prize-drawing for an Amazon Kindle as well as second and third place prizes.
Each day during the week participants who choose to take the challenge will receive a five-question, Brainteaser Challenge by email. Each completed quiz will count as an entry into the drawing.
