How to display older blog posts?

I noticed on my blog page, there is only recent posts of up to 30. How can I display my older posts?

Thanks

Use Summary block to display your blog posts. You can have up to 30 post per block and you can chain blocks together for as many posts as you want on one page. You use hidden categories to filter the posts. First 30 cat 1-30 second 30 give each post the cat of 32-60 or whatever name you want group 1, group 2 etc. This takes a bit of work but it works out great, as you can see here:

I have over 80 posts on one page categorized by subject. I used a second blog page to itemize the first, one blog for the posts, the second full of summary blocks. The summary blog is my front facing blog page, the actual bog is in the unlinked section of my site. You don't have to make yours as dramatic as mine, a new blank page with summary blocks on it will work quite well.
