Welcome to the world of electronic textbooks, often called ebooks or webbooks! This particular ebook has been created using the Pressbooks platform. If this is your first time using a Pressbooks ebook, this chapter will provide some basic information on navigation, download options, and special features in this particular ebook.

Basic Navigation

There are multiple ways to navigate through an ebook, either from the main title page or within the ebook itself. You do not have to register or have login credentials to use this ebook.

Starting from the title page, you can read the ebook on page 1 using the “Read Book” button. This is like opening a physical book to the first page. You can also scroll down to see all the ebook’s contents and go directly into any section or chapter by clicking on the chapter or section title. Some chapters may have a “lock symbol” next to them, indicating they are not publicly visible on the internet or password-protected; e.g., they may be designated for ERAU class use only. If you think you should have access to the content and do not, then you should contact your instructor for more information about how to proceed or to gain access.

Once inside the ebook, you have a few other options for navigation. You can return to the title page by selecting the ebook’s title or see all book contents using the “Contents” drop-down in the upper left corner. Like on the title page, clicking on any chapter or section title will take you to that part of the ebook. Finally, you can use the navigation bar at the bottom of the page to move forward and backward in the ebook (like reading a physical book in order).

Download Options

This ebook may be available to download in various formats, such as a .pdf for offline reading or other uses. You can return to the ebook’s title page to see what formats are available for download. In addition, download options will be available in a drop-down under the ebook’s cover image. Some interactive features are only visible in web-enabled versions of this ebook. Components removed in offline formats should be replaced with a warning and link to the online-only content.

Downloads may not reflect the most recent updates to the book.  The most up-to-date version will always be the webbook edition of this book.

Search Feature

Above the ebook’s title will be a search box with a magnifying glass symbol or a menu button that looks like three parallel lines in the upper right of the ebook. The search function will be available if you open the drop-down menu. This then gives a full-text search of the ebook and will return the chapters where the word appears. Put the term in quotations if you need to find a specific phrase. For example, “lift capability” will search for the phrase rather than the words “lift” and “capability” separately.
