Thanks to Reinhard F. Hahn (Ron) of Lowlands-L for very many suggestions and corrections.
Thanks to the following people who sent me comments and suggestions for links:
Claus D. Pusch
Iain Mac an Tàilleir
Thanks to Evan Antworth of SIL for providing the language subfamily pages in the Ethnologue database for me to link to.
Thanks to many others besides, who gave me suggestions before I started keeping track of their names.
I would be very grateful to anyone else who can send me corrections, suggestions for new links, or suggestions for links which should be removed because they have now been superceded. My aim is not to clutter the list up with large numbers of links, but rather to give, ideally, two to four good comprehensive links for each language - "two to four" so that there is some backup in case a site disappears or is temporarily unreachable. I aim to link both to information in the language for speakers of the language, and also to some descriptive information about the language accessible to those who do not speak the language.
