historical tidbits have been collected from various sources, mostly on the Internet.
As detailed in
this article, there
is a lot of wrong information that is repeated hundreds of times because most websites
do not validate with authoritative sources. On RF Cafe, events with
hyperlinks have been verified. Many years ago,
I began commemorating the birthdays of notable people and events with
special RF Cafe logos.
Where available, I like to use images from postage stamps from the country where
the person or event occurred. Images used in the logos are often from open source websites
like Wikipedia, and are specifically credited with a hyperlink back to the source where
possible. Fair Use
laws permit small samples of copyrighted content.
