I am a (really really happy) Readerware customer.
We also purchased the Opticon laser scanner - and together with Readerware the whole thing is a literal Godsend - we simply could not get our stuff cataloged without them.
Got over 3,000 books cataloged (probably about a thousand to go), and have not yet started using the Music and Video collections applications since time is tight - but again we simply would never be able catalog this stuff at all without Readerware - and a good scanner.
I hope ya'll are making some real money with this thing - you have well earned it!
