The library's plan is exceptionally innovative: circulation to the building's five stories is through the tower's staircase, separated from the reading rooms and stacks. The Main Reading Room is a soaring four-story brick-and-terra-cotta-enclosed space, divided by an arcade from the two-story Rotunda Reading Room. The latter has a
basilica plan – with seminar rooms grouped around an
apse (like
side-chapels) – the entire space lighted by
clerestory windows. Above the Rotunda Reading Room is a two-story lecture hall, now an
architecture studio. The Main Reading Room, with its enormous skylight and wall of south-facing windows, acts as a
lightwell, illuminating the surrounding inner rooms through
leaded glass windows. The three-story fireproof stacks are housed in a modular iron wing, with a glass roof and glass-block floors to help light the lower levels. It was designed to initially hold 100,000 books – but also to be continuously expandable, one bay at a time, with a movable south wall. Furness's perspective drawing highlighted this growth potential by showing nine-bay stacks, although the initial three-bay stacks were never expanded. Throughout the building are windows inscribed with quotations from
Shakespeare, chosen by
Horace Howard Furness (Frank's older brother), a University lecturer and a preeminent American Shakespearean scholar of the 19th century. The architect collaborated with
Melvil Dewey, creator of the
Dewey Decimal System, and others to make this the most modern American library building of its time. The Henry Charles Lea Library, a two-story addition to the building's east side, was designed by Furness, Evans & Company and completed in 1905. ==Rejection==
