At the top of every Astronomy Notes chapter document are links to the chapter index. The first link will display the chapter index in the main window. The second link will display the chapter index in another small window. Select the links in the index to go to the particular section you want. If you bring up a chapter index in the small window while another chapter index is displayed in it, the links will not work until you select the ``Refresh window'' link at the top. (Experienced javascript programmers: please tell me how to fix this problem!)
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!
