We resolve the entropy problem in the AdS3/CFT correspondence by introducing both the normalizable and non-normalizable bulk modes. On the boundary, the normalizable Liouville states gives us c=1 conformal field theory(CFT), whereas the non-normalizable Liouville states provide c = 3 ℓ \over 2 G CFT. Such (boundary) non-normalizable modes come from non-normalizable bulk modes which serve as classical, non-fluctuating bulk background and encode the choice of local operator insertion on the boundary. Since the non-normalizable bulk modes can transfer information from bulk to boundary, it suggests that counting of non-normalizable states on the boundary at infinity leads to the entropy(S=2 πr+ \over 4 G) of (2+1)-dimensional gravity with Λ= -1/ℓ2.
