Bookshelf files consist of the following:

• XSLT files : used for creating the HTML pages of a screenbook. These files are explained in a later tutorial in this series.
• HTML files : for example, the bookshelf table of contents
• cp_ files : any file beginning with cp_ will be copied by Screenbook Maker from the bookshelf folder to the screenbook folder whenever a screenbook is created or edited.
• PNG files : for the icons used by the screenbook HTML pages, and other pages
• sbook1.css : the CSS file for the screenbook (explained in a later tutorial in this series)
• sbook.js : the javascript for the screenbooks in the bookshelf
• sbooktoc.xml : the master file for creating the table of contents HTML
• options.xml : bookshelf options, for example, a list of FTP sites for the bookshelf
