Question about Arduino Cookbook

This must be a stupid question to ask but really i can't figure it out!

There are schematics in Arduino Cookbook which some components (i.e resistors, transistors...) don't have values and only say "See TEXT for component value.

the question is, Where am i supposed to see? Where is the 'TEXT' to see? :~

Text, usually is an article, describing a project.

If you go to...

... you can browse the book's contents. I don't know if you can read EVERY page, but you can read many.
