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.
