When I SEARCH and BROWSE BY TITLE, and click on the zero "0", two books show up.  They have no titles and no authors listed for them.  I can only can tell they are paperbacks.    I stumbled on these by accident  and was just curious what  these two books were about.  Mysteries perhaps?

Hmmmm... that is interesting.  They are posted by the same person and if you search them by the "ISBN" it comes up blank.  And if you enter the ISBN as tho you were going to post it, that also comes up blank.

I clicked "Order this book" and retrieved two different members who posted these two mysterious books.  One of them had another such a book on his/her shelf with no title and no author.  That makes three mysterious books in the PBS with no titles or authors.  Weird.      

Those two were entered into the system by the members themselves as non-ISBN books.  Which a fine example of double checking the data before pressing enter because the data can't be edited or deleted by us, only by the PBS team I think.

Actually, they can't be edited by us, either. I believe Robert could, but he is always busy working up some new great thing for PBS like postage paid wrappers and such! So, he's probably not going to get them done, and they will just stay there to annoy me and others that wish they could edit them, like the person that accidentally made those :)
