When this happens, the IP address for your machine is not being recognized by our computer. This failure is caused by one of three things:

• Your institutional subscription has not yet been activated
• The person who "activated" the online subscription did not enter in all needed IP addresses for your institution
• The person who "activated" the online subscription does not realize that some subnets of your institution are routed through a proxy server

What should I do?

1. Send us Feedback so we can begin to diagnose the problem
2. Talk to your librarian, and let them know you are having trouble

A subscription on paper and a subscription online are two different things. You or your institution must separately subscribe to the Online Edition to have access to the full text online. See How to Subscribe for details.

The subscription fee allows for unrestricted Internet access at one location. Any user connecting from an authorized computer on your institutional network will be allowed access to MBC Online.

For the most part, an Institutional Subscription authorizes use at a localized site. A "site" is an organizational unit, and may be academic or nonacademic. For organizations located in more than one city, each city office is considered a different site. For organizations within the same city that are administered independently, each office is considered a different site.

For example, each campus in the State University of New York system is considered a different site, and each branch or office of UpJohn Laboratories is considered a different site.

When someone attempts to use MBC Online, our server checks to see if the requesting computer is within the list of internet IP address provided by a subscribing institution. If it is, the reader will be able to use all those services enabled for institutional readers. For institutional subscribers, there are no user names or passwords to remember, and there is currently no limit on the number of readers from your institution who may access MBC Online simultaneously.

If readers want to access MBC Online from computers that are not part of your institutional network, they must dial in through the institution's server and then use the institution's IP address.

If your institution has a subscription, you'll automatically have access to the entire site without having to sign in. You'll also see a button at the top of the page confirming you're already signed in as part of an institution.

If your institution has not subscribed, please contact your local librarian.

Yes, when you buy a subscription to MBC Online, you have access to all years of the database.
