Open Source Software Libraries :
“Open source software is not something to be afraid of! It’s software that you can modify, fix, add to, and distribute to others. Benefits are numerous, including having the ability to create good software that works for you and your library, all while paying a fraction of the cost that you might spend on proprietary software. This website introduces librarians to using open source software and provides tips for implementing and evaluating your transition, ideas for funding, and suggestions for open source software to use in your library.”
