Maintenance Notice

Copyright Clearance Center's web-based services are currently available.

We are sorry you are having difficulty accessing our sites. We have recently upgraded our systems to a faster internet connection. Since you have reached this page, you are not accessing our site from our new connection. The most common reason this occurs is due to your Internet Service Provider continuing to use expired DNS entries. Please contact your Information Technology Department or Internet Service Provider to have any DNS caching services updated to use our new IP ranges.

Thank you
