In the realm of Blue Amberols , the Alan Sutton book :
" EDISON BLUE AMBEROL CYLINDERS 1912 to 1929 "
covers the subject in fabulous detail . Anyone with more
than a few Blue Amberols needs ( or already owns ) this
authoritative work . It is available from the Mainspring Press .
Yes it is nice to have a list of sorts available on Wikipedia
and it may prove useful to some collectors .
