The Free Library System is designed to be easy to use and flexible, but one cannot deny the fact that it's free. It's even got it in the name. So the biggest investment in installing this system is time. Who would want to invest in a system like this?

1. An independent library who is just moving to an online catalog.
2. Libraries who need the flexibility only an open source program can offer.
3. A group or consortium of libraries who want to be able to share their databases for searching and circulation.
4. Librarians sick of buggy software and unintuitive interfaces. (Not to say that fls will not have bugs during its development, but when they do pop up, they can be squashed in no time, thanks to its open source license.
