>From the FAQ:

,----
| _What is the Overview/NOV database?_
| 
| The Overview or News OverView (NOV) database was designed by Geoff
| Collyer.  Its a more generalized database, it it contains *no*
| threading information, just the information needed to thread.  The
| overview database is just a database of files, one for each group,
| containing a reference to each article, with seven or eight of the
| most popular headers.  Thus, the newsreader client can get most of the
| information it needs to thread, but it does the threading the way it
| wants to.  Yes, the downside is that now the threading occurs on the
| client's CPU, but that's not as expensive as it may seem, if done
| properly.
