Including link + icon in heder bar

[aridus]

I have completed two short books using msmbstyle. These books are going to be included in the new website of the conservation science journal of which I am the editor. To be able to incorporate the books into our own site we need to add an icon and link in the header bar of each, so that a reader can return to the main site from the books.

However, I cannot figure out how to do this!

If you have any suggestions, I would be exceedingly grateful. Thank you.

Obviously that should have been 'header' (rather than 'heder'!) in the subject.
