discontinued the policy of marking broken links, and are
now deleting links within seven days of the day they become broken, using
a scheduling system that takes temporary problems into account. This
schedule enables good links to be retained long enough for problems to be
corrected, while still removing those with permanent problems in a timely
fashion. We attempt to locate items that have been moved, and
to identify typing corrections in newly added resources prior to deletion,
and we retain redirected links so that those who move files but redirect
the urls will continue to be listed until they have updated their links in
our system. However, we do consider it the responsibility of those
who wish to be included in our project to enter their new changes in the
appropriate sections of the Library.

Library Search Engine to see if your link has been removed. If so,
please add it back so everyone will be able to find your resource.
Most pages have a "Links verified" link near the bottom of the page, so
that anyone who wants to can quickly check the immediate status of all
links on the page. The link maintenance schedule includes all
the pages in the library.
Timeout, and Overload errors may be re-run for several days before removing
selected valuable links, because these problems are often temporary and may be due to
network problems rather than actual broken links. However, "File Not
Found" errors will normally be removed as they come up unless we can
find the new location, since usually these are due
to files having been removed from their known location.
