The State Library has posted on the Digital Library, an image of the original Carver Branch Library floor plan here: https://www.louisianadigitallibrary.org/islandora/object/state-lhp%3A1166 .
This is the Selman Field building, originally brought in and placed behind the old Miller Roy building, then converted to a library. We have several interior shots in our collection, and the best one is here: https://www.louisianadigitallibrary.org/islandora/object/oplib-arc%3A19. It is a neat little tidbit of library history!
