For the last several weeks, if you go to older issues, for example:
http://slashdot.org/index.pl?issue=2010610
The bottom page navigation links are
< Today's News | June 14 >
This used to be the correct (for the given date)
< June 11 | June 9 >
Note the pages pointed to are incorrect also, it's not just the text:
<link rel="prev" title="June 14" href="//slashdot.org/index.pl?issue=">
<link rel="next" title="Today's News" href="//slashdot.org/">
Thanks
