The site "History of Phrenology on the Web" at http://pages.britishlibrary.net/phrenology gives
an extensive overview of the early history of phrenology. It contains
a number of scientific essays from research by John Van Wyhe at Cambridge
University, as well as an extensive bibliography.
For retrieving historical information, this site is extremely well documented
and most probably the most comprehensive web source available.
A on-line article about Phrenology has recently
been published in Brasil. Although taking a critical viewpoint
towards the Science (being written by an academic neuropsychologist),
it is nicely presented in web-page format and definitely worth a
look.
A comprehensive site concerning Phrenology and
its influence on 19th century literature has been compiled by Prof.
Peter Friesen of Plattsburgh University. It contains a full online edition
of George Combe's1834 American edition of "Elements of Phrenology",
at http://www.plattsburgh.edu/faculty/friesep/combe1.html
A web site has been published on the publication
of the book by Charles Colbert "A Measure
of Perfection: Phrenology and the Fine Arts in America". The site
shows some interesting phrenological drawings and can bee seen at: http://www.bc.edu/bc_org/avp/cas/fnart/phrenology/
The London Phrenology Company
was founded to revive interest in Phrenology and act as a source
of books, busts, posters, learning and communication about
this ancient science. It has its
own website at http://www.london-phrenology.com.
