The best on-line resource I found about Moon is by the Brighton Society for
the Blind (http://www.bsblind.co.uk/full/index.htm):

- Table of contents: http://www.bsblind.co.uk/full/moon/moonbar.htm

- An introduction (beware, it uses frames):
http://www.bsblind.co.uk/full/moon/typeindx.htm

- Three biographies of W. Moon:
http://www.bsblind.co.uk/full/moon/wmoon1.htm
http://www.bsblind.co.uk/full/moon/wmoon3.htm
http://www.bsblind.co.uk/full/moon/wmoon5.htm

- A writing by W. Moon ("Incidents..."):
http://www.bsblind.co.uk/full/moon/wmoon4.htm

- Links: http://www.bsblind.co.uk/full/moon/moonlink.htm

- And more.

Also the Royal National Institute for the Blind
(http://www.rnib.org.uk/welcome.htm) has some material about Moon:

- A short intro to Moon: http://www.rnib.org.uk/braille/moonc.htm (NOTE:
unluckily the picture of the Moon alphabet does not show)

- A short history of Moon: http://www.rnib.org.uk/wesupply/fctsheet/moon.htm

- A Moon TrueType font: http://www.rnib.org.uk/wesupply/archive/welcome.htm

- Moon products: http://www.rnib.org.uk/wesupply/products/prodcat/catmoo.htm
