The masthead is the banner at the top of page 1, which contains the title of the newspaper, the number, date, number of pages, and price, and is flanked by two advertisements. Update the number, date, and number of pages.
Now you need to find the templates that correspond to the ads that appear in your issue. There are detailed template instructions here. Following the indications there, copy the xml text of template you need.
Next, you must paste this text into the right place in your xml document. The two ads flanking the masthead go right after the title, date, and so on, and before the </div>
tag that closes the masthead:
Then insert the first ad in the first column after the masthead after the <cb n="1"/>
tag in the advertising section division, and proceed inserting ads all the way to the end of the page.
At the top right hand corner of your editing window in Oxygen, there is a square that will be either red or green. If it’s green, your document is well-formed, which means that it conforms to TEI XML standards and will be searchable and useable. If it’s red, the file contains errors that you must fix before you submit it. The errors appear as red lines on the right hand scrolling column. Click on a line to see the error described at the bottom of your editing screen.
One common error that prevents a well-formed document:
<?xml version="1.0" encoding="UTF-8"?>
lines at the opening of the xml document.
