Pronunciation note
Library, with one r -sound following close upon another, is particularly vulnerable to the process of dissimilation—the tendency for neighboring like sounds to become unlike, or for one of them to disappear altogether. The pronunciation
[lahy-brer-ee] /ˈlaɪ brɛr i/ (Show IPA)
therefore, while still the most common, is frequently reduced by educated speakers, both in the U.S. and in England, to the dissimilated
[lahy-buh-ree] /ˈlaɪ bə ri/
[lahy-bree] /ˈlaɪ bri/ .
A third dissimilated form
[lahy-ber-ee] /ˈlaɪ bɛr i/
is more likely to be heard from less educated or very young speakers, and is often criticized. See colonel, February, governor. Unabridged

Word Origin and History for library

place for books, late 14c., from Anglo-French librarie, Old French librairie "collection of books" (14c.), noun use of adj. librarius "concerning books," from Latin librarium "chest for books," from liber (genitive libri) "book, paper, parchment," originally "the inner bark of trees," probably a derivative of PIE root *leub(h)- "to strip, to peel" (see leaf). The equivalent word in most Romance languages now means "bookseller's shop." Old English had bochord, literally "book hord."

library in Technology
programming, library
A collection of subroutines and functions stored in one or more files, usually in compiled form, for linking with other programs. Libraries are one of the earliest forms of organised code reuse. They are often supplied by the operating system or software development environment developer to be used in many different programs. The routines in a library may be general purpose or designed for some specific function such as three dimensional animated graphics.
Libraries are linked with the user's program to form a complete executable. The linking may be static linking or, in some systems, dynamic linking.
