Frequently Asked Questions About Institutional Subscriptions
  1. My institution has a subscription to JCO, and access to JCO online, but I'm not able to see the full text of articles. I'm prompted for a username and password. Why is this happening?

    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, or was activated for one workstation only;

    The person who activated the online subscription did not enter all of the necessary 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 diagnose the problem.
    2. Notify your librarian of the problem.

  2. My library subscribes to JCO, and I can't get access to it online. Why?

    Your institution has not yet activated its institutional subscription to JCO online. All institutional subscribers to the print journal qualify to receive access to the online journal. However, your institution may have a print-only subscription. Notify your library that you would like access to JCO online, and ask your librarian to activate the online subscription.

  3. Who from my institution can access JCO Online?

    The basic subscription fee allows for unrestricted Internet access.

  4. What is an institution?

    An institutional subscription with a site license agreement 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 a separate site. For organizations within the same city that are administered independently, each office is a separate site.

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

  5. How does access work?

    When someone attempts to use JCO online, our server checks to see whether 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 is currently no limit on the number of readers from your institution who may access JCO Online simultaneously.

  6. How can I tell if my institution has subscribed to JCO online?

    If your institution has a subscription, you automatically have access to the tables of contents, abstracts, full-text searching, full text display, PDFs, Medline and GenBank links, and future tables of contents. You also see the name of your institution at the top of the page.

  7. Can my institution subscribe only to the electronic version?

    At the present time, JCO print and online subscriptions are sold as a package.

  8. Will we still be able to get the print version?

    Institutions and individuals will be able to receive the print version for the foreseeable future.

  9. If our JCO Online subscription expires and at some later date we reinstate our subscription, will we have access to all years of the electronic version?

    Yes, when you buy a subscription to JCO online, you have access to past issues from 1999-present.

    At JCO Legacy Archive, online full-text back issues from 1983 to 1998, can be purchased for a one-time fee.

  10. How can I access JCO online if I am not an ASCO member and I don't have access through an institutional subscription?

    You may purchase the JCO as an Individual subscriber. Without a subscription you have access to the table of contents, abstracts, and full-text searching (but not full-text viewing) at no cost and without having to register.
