Hello, everyone.  We are evaluating our serials collection for possible
weeding.  One of the items on our list is the National Union Catalog.  
Does anyone know whether the NUC has ever been put online?  It could be
either a free or paid database.  We are concerned with maintaining
access to the historical content that the NUC is known for.
