Can I only display the last 3 posts/blog entries?

Hi,

Is it possible to only display the last three (3) posts? I need to be able to shorten the page length, and if I only display the last three posts, that would suit just fine.

I don’t want to delete the earlier posts, as I would like to keep them for historical purposes.

Your advice would be appreciated, with help on how to do it.

Many thanks,
Steve
