Your press information page is absolutely vital. It should carry information that the press may wish to include in articles. You should also provide high-resolution images (profile photos), a list of your books, awards, honours, achievements, and any other published work. You should also link to your press releases.
If a member of the press has become interested in you, they will come looking for more information. Should you provide everything they need, they will continue writing their article about you. If not they may fire off an email and go and write about someone else. Which is why you must be short, to the point, and cover all the points they might need.
There are other (optional) things you can add to your press page. If any information is not (obviously) found elsewhere, put it here or link to it.
