This guide is free to use: no advertising, no sign-in, no tracking cookies. Every photograph and recording is under a Creative Commons licence or in the public domain, and every source is credited. What it costs is mainly time, plus the hosting and the domain name.

Contributions go to a private individual, not to a registered charity: they are not tax-deductible and nothing is given in return. No newsletter, and no personal data is kept.
