Warning Messages

To protect our publishers' copyrights, Books24x7 has implemented a warning system that advises users when their activity on the site could be in violation of certain terms in our Membership Agreement that pertain to downloading or storing pages for offline use.

The content on the site is licensed to Books24x7 with the understanding that all reasonable measures will be taken to prevent saving it offline unless expressly permitted.

The criteria for these warnings have been determined after careful review of usage patterns that have been associated with content downloading and offlining over the past four years. Some behaviors that seem legitimate to a subscriber may appear consistent with these patterns, and will trigger warnings.

This page is intended to clarify the usage patterns that trigger these warning messages.


Users will be given two warnings about problematic behavior and will be asked to acknowledge receipt of these before being able to access content again. If the problematic behavior continues, a third notice will alert the user that the account has been disabled.

Examples of Problematic Behavior

  • Access of majority of pages in a book within a given time period.
  • Unattended retrieval of content.
  • Deliberately loading up a browser cache for offline use.
  • Questions and Answers

    1. How can I skim through a book without triggering a warning?
    2. Limiting the "skimming" to the sections of a book which are of interest is advisable.
    3. Will I trigger warnings if I access too much of a book?
    4. We have learned a great deal about how online reference materials are used, and applied this in identifying usage patterns that tend to indicate harvesting activity. The amount of book content that is accessed can be one of these indicators. In the majority of cases where this has occurred, there have been additional indications of offlining activity.
    5. I just logged in and started to read when a warning came up!
    6. Sometimes activity in sessions prior to the one in which the warning displays has also contributed to calculations that lead to a warning message.
    7. Also, account sharing can contribute to violations, since the usage is considered cumulatively. If you think someone might be using your login, change your password from the "Preferences" link in the left frame of "My Bookshelf."
