Initial Code 
def previous_post
  self.class.first(:conditions => ["title < ?", title], :order => "title desc")
end

def next_post
  self.class.first(:conditions => ["title > ?", title], :order => "title asc")
end
You can then link to those in the view.

<%= link_to("Previous Post", @post.previous_post) if @post.previous_post %>
<%= link_to("Next Post", @post.next_post) if @post.next_post %>
