From the cooperative bibliographic experience hosted on this web site we have learned more from criticisms than probably the author and us intended at the beginning of this experiment. It is somehow with a bitter taste that I conclude by saying that the readers expected more also in terms of sharing a bibliographic resource available for free and maintained by the users. Beyond discussions and issues related to the original theme and what was missing, I am particularly grateful of the comments by Marlene Di Costanzo as they express very well the spirit of the initiative, i.e. being critical yet propositive at the same time. Many thanks also to all other that have participated with their suggestions and ideas.
