Search the library catalogue to find books on marketing. You can do keyword searches as well as subject searches, which utilize the Library of Congress Subject Headings to locate items on the same subject. Some relevant subject headings include:
Notice all of the sub-headings beneath the major subject terms which allow you to get more and more specific in terms of topic or geographic location.
These same terms (and more) will work as keyword searches, but you will get many more (and possibly irrelevant) results using a keyword search. Try both and take it from there. If you search any term in the 'subject' field, the catalogue will try to suggest related subjects for you to try, as well as more sub-categories of the subject. Of course, if you know the title or author of a book, you can search the catalogue using those fields as well.
You can also do an advanced keyword search and restrict the 'material type' to limit your search to e-books only.
