wp_get_archives may not be the best choice of function for what you are looking for.
not clear from your description exactly what you mean. When you say display “on a regular webpage”, are you referring to a WordPress static page, or an HTML page that is not at all part of WordPress?
You may be better off using a custom query, which would include the description and permalink and title – your own custom WordPress loop. For details look at this article

Feel free to ask further questions.
What I mean is usually when you go to a listing of blogs, you get the title of the post and then either the entire post or a condensed version underneath it. That’s what I want. I want to display the title of the post (which it does now) and then a truncated version of the post itself. Like you normally see in a blog only on a page.
The template tag, wp_get_archives(), does not have the ability to display anything but the post title.
Another example of what stvwlf was suggesting may help you–see the Page of Posts example in the Pages article.
