What is expansion?

expansion meaning in Information Science terminology / glossary / dictionary is:

Enlargement of the space available in an existing library facility. The amount of floor space in a library is usually increased by moving nonlibrary functions, such as a computer lab or offices, to other facilities or by adding a new wing or floor to the existing structure. Some libraries are designed with a knock-out wall and sited on property large enough to accommodate future expansion. In libraries critically short of space, a new addition may dwarf the original structure. Major library expansions are reported annually in Library Journal and in Library and Book Trade Almanac. Compare with new construction and renovation.Also refers to the development of an existing class or subdivision in the schedules or tables of Dewey Decimal Classification (DDC), usually to accommodate advances in the literature on the subject requiring more specific notation.
