Open Source Library Software
Open Source software is software that is licensed under one of several Open Source licenses such as BSD, GNU General Public, GNU Lesser General Public, Mozilla Public, and others. Whether they know it or not, every library uses some Open Source software. Linux, Apache Web Server, OpenOffice, GIMP, Audacity, and Firefox are examples of Open Source software many libraries use.
In the last several years, two Open Source Library System products have also gained in popularity: Koha and Evergreen. Both are full-featured library products. We have been working on keeping track of the features that are and are not yet available in each product. To check out what we've learned, go to our Features page (in development) where you can search for specific features and even create your own list of features (in case you want to come back later and see what's changed or perhaps use that list to generate an RFP).
