I love Readerware. It is one of my favorite and most used programs and has saved me innumerable hours for cataloging my books of which I have almost 600. Without Readerware the catalog would be a pipe dream.Sure, I could have filed the books using the Dewey Decimal System , but locating them would be hard (I have found many duplicates thanks to Readerware because i could not physically locate the book! You have saved me money from not buying duplicate copies because I could not find where I put the book! Now before I buy any book I check Readerware to be sure I do not already own the book!
