First, hate to sound like a broken record but THANK YOU to you all for such great advice and suggestions. Eveything is working accordingly. I think what happened was Calibre on my netbook wasn't closed - as a matter of fact I know it didn't because I had the setting marked to keep it in my tray. I have removed that setting so when I close Calibre on any machine, it closes out completely. I removed one of the books I put in last night, re-added it back into Calibre - giving Dropbox enough time to synch. Once it completed, I went to my desktop and LO AND BEHOLD, it showed up in Calibre. I am so happy that I have worked this out because now I can access my library from both computers and this is a terrific thing.
