The Australian Museum has an interesting online exhibit entitled, “Death: The Last Taboo.” From the site intro:

Throughout the world, death and the rituals that surround it are steeped in taboos. Death is celebrated, embraced and feared. Around death and the dead, cultures put in place diverse restrictions and practices associated with clothing, food and ritual. This website explores what happens to us when we die and the different ways we deal with death.

The site covers a range of subject material, from safety coffins to autopsies, and includes multimedia and links to other sites. The Victorian section has some nice photos of traditional mourning attire and mementos mori.
