I'm looking for recommendations on good books relating to cemeteries, grave carving, death customs and things of that nature.

I'm a member of a few local cemetery commissions, and am contemplating on writing my own book on New England cemeteries, and am always looking for new research material.

I already have the following books in my collection:

• The Victorian Cemetery - Sara Rutherford
• The Victorian Undertaker - Trevor May
• Silent City On A Hill - Blanche M. G. Linden
• Maine's Coastal Cemeteries - Karen Batignani
• Cincinnati's Cemeteries: The Queen City Underground - Kevin Grace
• North Burial Ground, Providence Rhode Island - John Sterling
• Rest in Peace: A Cultural History of Death and the Funeral home in 20th Century America - Gary Landerman
• The Sacred Remains: American Attitudes Towards Death, 1799-1833 - Gary Landerman
• Coventry, Rhode Island Historic Cemeteries - John Sterling
• Exeter, Rhode Island Historic Cemeteries - John Sterling
• From Slate to Marble 1770-1870: Gravestone Carving Traditions in Eastern Massachusetts - James Blachowicz
• Rest in Peace: A History of American Cemeteries - Meg Greene
• The Victorian Celebration of Death - James Curl
• The American Resting Place: 400 years of history through our Cemeteries and Burial Grounds - Marilyn Yalom
• A Graveyard Preservation Primer - Lynette Strangstad
• Gravestones of Early New England, and the Men Who Made Them, 1653-1800 - Harriette Merrifield Forbes
• Graveyards of North Kingstown, Rhode Island - Althea McAleer
• The Burying Place of Governor Arnold - Alice Brayton
• Beautiful Death: The Art of the Cemetery - David Robinson
• Cemeteries and Gravemarkers - Richard Meyer
• New Orleans Cemeteries: Life in the Cities of the Dead - Florence Mason
• Going Out in Style: The Architecture of Eternity - Douglas Keister
• Soul in the Stone: Cemetery Art from Americas Heartland - John Gary Brown
• Graven Images: New England Stone Carving and its Symbols, 1650-1815 - Allen Ludwig
• Stories in Stone: A Field Guide to Cemetery Symbolism and Iconography - Douglas Keister
• The Last Great Necessity: Cemeteries in American History - David Charles Sloane
• The Puritan Way of Death: A Study in Religion, Culture and Social Change - David E. Stannard
• Saving Graces: Images of Women in European Cemeteries - David Robinson

Any other recommendations would be greatly welcomed.  I keep doing searches for cemeteries on PBS, but since it's such an odd subject, I never come up with much!

I think I've got just about everything on New England cemeteries, but I am really interested in expanding my knowledge base to outside of my Puritan Death-Heads and Victorian angels.
