I forget why I made it so big, but perhaps because I was thinking of
adding partitions to / of uncertain size. 

Thanks for your  partition size recomendations. This has always been in
interesting debating point for linux users, it seems.

Ncdu was new to me and I tried it. I did:

  $ ncdu -rx /
 
and it says total disk usage is 130.7MiB. I take this to mean total
partition usage is 130.7 Mb. Although this seems extraordinarily big, it
is well less than the 500 Mb partition. It seems that 95 Mb for lib is
too big, and when I roughtly added up the size of the files in /lib, it
seems far more than that. It is also a lot different than what df says,
which is that the partition is 100% full with 474.4 Mb of files.
