Writfinder is a library system that users can use for free (and at their own risk). It is designed for libraries that are relatively small or containing less than 100,000 copies. Soon you will be able to fetch your own copy of the system on GitHub and then you can set it up on your own Internet server, if needed with assistance from your web service provider.
Meanwhile, you can take a look at the system here (test.writfinder.com).
