At the bottom of every chapter document is a link back to the the Astronomy Notes homepage, the date the document was last updated, and a link to the web page for how to contact me. You will see my name ``Nick Strobel'' highlighted in some way like it is here. Select that link to bring up my contact page. If you have a question about a particular part of the Astronomy Notes, be sure to tell me what section you are referring to.
If you are sending email from a computer at a library, be sure to include in your message to me an email account where you can be sure to receive a reply. If you like this astronomy web site, then put it in your web browser's Bookmark database (it may be called ``Favorites'' in your web browser). That will save you the trouble of typing out that long URL address!
