Blogger pages let you to publish static information on stand-alone pages linked from your blog. For example, you can use pages to create an About This Blog page that discusses the evolution of your blog, or a Contact Me page that provides directions, a phone number, and a map to your location.
You create a page similar to how you write a blog post. From Blogger in Draft click Posting | Edit Pages tab, then click New Page. (Note: you can create up to 10 pages)
Once your page is published, you can link to it from the new Pages widget. The Pages widget lets you add links to your pages as tabs at the top of your blog, or as links in your blog's sidebar. (Note: existing third party templates may not support pages as tabs, but pages can still be added as links in your blog's sidebar)
In the Pages widget, you can decide which pages will have links, and in what order they will appear. You can also choose whether or not you want links automatically created for pages when you create them by checking or unchecking the box to the left of Add New Pages by Default.
* For those of you that have custom templates, your custom template may not automatically support Pages as horizontal "tabs".
