Open source software has become widely adopted by libraries as both integrated library systems and other applications. There are strengths and weaknesses to both developing open source software internally ("build") versus purchasing commercial options or borrowing existing open source code to customize ("buy" or "borrow"). Building requires significant technical resources but allows for total customization, while buying relies on vendors for support but reduces the technical burden. Overall, open source aligns with library values of sharing knowledge and being open to all.

2. “The open source community is a natural ally of the library community. Both try to enrich their members through sharing and disseminating knowledge, and both are open to everyone, private or public, commercial or non-commercial.” - Evergreen Web sitewww.open-ils.org

3. Background OSS linked to early computer days Software was shared, programmers paid for programming services OSS model replaced by limited access = $$ OS Initiative created in 1998 allowed user to: make and distribute copies of programs view the source code of software make improvements to program OS does not necessarily mean free- just that users have the freedom of above rights

5. Strengths and Weaknesses Build Buy Pros Total customization Quick response to issues Cons Need highly technical staff Time involved to create and work out bugs Difficult for migration/expansion Pros Free from burden of creating and maintaining Less need for tech staff Cons Dependent on vendor Time delay on issue resolution Must wait for next version release and hope for the best

6. Borrow Pros Can make changes to software to fit needs Developed in the open Cost effective More choice Quicker updates and issue resolution Cons May need tech staff May feel less secure about tech support

7. “Open source… was developed in the open, not secretly by a small group. Many eyes looking at software makes better code.” - Molyneux (2009)
