The Munising Public Library is part of the high school building, but as far as I could tell, it is a separate entity, unlike Pipestone, MN, where the library is half a community library, half the high school library. I didn't have a chance to ask about this because this was not an inquisitive, chatty sort of place.
The high school connection was clear, however, in the large class photographs from various years of the William G. Mather High School. The newest of these pictures were from the 60s, and so probably from an earlier building.
To the right of the entrance is a pleasant sitting area for browsing, with chairs upholstered in book-design fabric. There are about a dozen computers, and the science theme of the summer reading program is reflected in the science objects, including a microscope and various jars with biology specimens displayed on a shelf.
The children's area has two computers, round tables with wooden chairs, a child-height, slant-topped box/desk that appeared to be intended to hold large reference books for easy reading, and a collection of floor chairs/backrests. Picture books are labeled "E," which is defined on a sign as "Elementary." "J" designates Junior fiction. Science books were displayed, supporting the summer theme.
