  5. Wood-paneled Library and Board Room on second floor
  6. Original Lecture Hall[a.k.a. Little Science Theater] Seating

The seating in the Lecture Hall is original 1939 seating. This original seating should be restored, NOT replaced. One company which specializes in seat restoration is Country Roads, Inc. of Greenville, Michigan; this company restored the seats in the 97-year-old concert hall of Boston's New England Conservatory of Music: Jordan Hall, in 1995. To meet present-day fire codes, the Lecture Hall's current seating capacity of 250 would have to be reduced to around 175-200, to allow the addition of two new aisles along both Lecture Hall walls[currently, the Lecture Hall has only one central aisle].
