Books whose height is too high for a regular sized shelf. They are designated by a (+) in the call number. Books may also show a double oversized designation by a (++). NOTE: Oversized books are shelved at the very end of each letter section. This can be very confusing. Each call number section has regular size (B-BZ) followed by oversize (B-BZ). For example BX1920.A7+ C3 does not get shelved with the regular BX1920s, it is shelved after ALL the B regular size books.
