Here is a great article listing resources for children's book written by Maine authors or which have Maine as the subject. Remember that the Berry Memorial Library has a large selection of Maine book, but not all of them!
The library recently lost a good friend in Mert Waterman. Mert was a Trustee for the Berry Memorial Library for over 50 years and he helped the library in more ways than can be mentioned. His dedication and friendship will be missed.
