The paperback has several references to Internet pages.
It is impractical to provide the complete URL for each reference in a paperback.
A web page enables a clickable link to a reference.
Here are the page numbers and each citation.
Sometimes a single page can have more than one reference.
Each line begins with a link showing the page number and its target, which is either
a typical web page (URL) in html format, or
a pdf file, or
a YouTube (YT) video URL.
page numbers are in the paper back edition.
