Hi, sueinspain!
You might try the Check Library option (Library Maintenance => Check Library). The problem is that you used the OS to put books into the calibre library but calibre's library database thinks they are still deleted. After the first pass, it should ask if you want to check if the files in the library match the information in the database. This should find the files and allow you to restore them.
I did that once courtesy of a much younger relative. My workaround was to move the files from the Recycle Bin to a temporary directory and then add the books from that directory back to calibre.
BTW, these messages would have been better posted in the calibre thread.
