+This is an example to break up long lists into several pages. It uses one url (get) variable "?offset=xxx"
+{{{
+def item_index(request):
+    offset = int(request.GET.get("offset", 0))
+    item_count = items.get_count()
+    limit=50
+    if (offset + limit) < (item_count - 1):
+        new_offset = offset + limit
+    else:
+        limit= (item_count - offset)
+        new_offset = False
+    latest_item_list = items.get_list(order_by=['-date'], offset=offset, limit=limit)
+    return render_to_response('item/list', {
+        'latest_item_list': latest_item_list,
+        'item_count': item_count,
+        'from': offset + 1,
+        'to': limit,
+        'offset': new_offset,
+    })
+}}}
+
+This is the template I use. It’s a very simple one, only displaying a row counter and a date column:
+
+{{{
+{% if latest_item_list %}
+    <p>
+    {% if item_count %}
+        There {% ifequal item_count "1" %}is{% endifequal %}
+        {% ifnotequal item_count "1" %}are{% endifnotequal %}
+        {{ item_count }} item{{ item_count|pluralize }}.
+    {% else %}
+        No itemcount provided to the template
+    {% endif %}
+    You are looking at {{ from }} to {{ to }}. 
+    </p>
+    <table width="100%">
+        <tr>
+            <th style="text-align:left;">#</th><th style="text-align:left;">Date</th>
+        </tr>
+    {% for item in latest_item_list %}
+        <tr>
+            <td>{{ forloop.counter }}</td>
+            <td>{{ item.date }}</td>
+        </tr>
+    {% endfor %}
+    </table>
+{% else %}
+    <p>There are no items available.</p>
+{% endif %}
+<p>
+{% if offset %}
+    <a href="?offset={{ offset }}">next</a>
+{% else %}
+    End of list.
+{% endif %}
+</p>
+}}}
