References

As distinct from How To Guides or Skills which change as technology changes, references tend to be documentation with an ISBN.

Once we could find things on Google, but omnipresent marketing directs us to profitable sites, and we see the same information over and over again. There is scope for a list of documents on things like image formats or government regulations. This will be the ones I find.

All of this is available online, from some very good sites, but the commercialisation of the internet means every man and his dog seems to be buying clicks for profit, by providing inferior copies of genuinely useful sites. You haven't got the time to wade through all that. Feel free to contribute.
