I want to know the answer to the following question:
How many miles of shelving are in BYU's Harold B. Lee Library?
All the background I'm provided with is that "BYU's Harold B. Lee Library (also known as "HBLL"), which The Princeton Review ranked as the No. 1 "Great College Library" in 2004, has approximately 8½ million items in its collections, contains 98 miles (158 km) of shelving, and can seat 4,600 people.". Is that enough to answer the question?
