I really struggled to find a decent program to act as a book library. There was one "un-named" program that offered a free version to try but was so limited in functionality that it was impossible to get a realistic idea of its capabilities. I came across a few that were functional but no longer supported and had no web lookup facility. I knew what I was looking for and the functionality I expected to find. I was beginning to despair until I came across Readerware.
From the beginning it was easy to grasp and the web lookup functionality was better than I expected. I used it for a few weeks before I paid for it and have never regretted it since.
The support is fantastic and better than any I have ever come across.
If you are looking for a program to catalogue your books then do not hesitate to buy Readerware Books.
