Smart Archives Reloaded allows you to display a list of posts grouped by year and month. It also provides several interesting navigation elements.
Format list:
<ul>
<li>list = a list of posts grouped by month</li>
<li>block = a compact block of links to year and date archive pages</li>
<li>menu = a two-level menu with links to year and date archive pages</li>
<li>both = block + list (<a href="http://scribu.net/archive" rel="nofollow ugc">example</a>)</li>
<li>fancy = menu + list + JavaScript (<a href="http://www.conceptfusion.co.nz/archive" rel="nofollow ugc">example</a>)</li>
</ul>
