[Web4lib] Big OPACs?

[Roy Tennant]

The Melvyl catalog at the University of California has 13,382,289 bib  
records, but as I'm sure Bernie appreciates merging records is more  
black magic than either an art or a science, so this should not be  
considered an accurate count of what a human being might consider to  
be items unique enough for a different bib record. Suffice it to say  
that any catalog with multi-million records is a significant beast  
that keeps one or more people up at night.
