Wiley Online Library adds CAPTCHA to prevent systematic article downloads


Wiley Logo

Dear Librarian,
Wiley has introduced a new security feature for access to articles through Wiley Online Library. This is in order to prevent systematic downloads of content and also to thwart hackers from creating other security risks for both library and vendor.

You may have encountered CAPTCHA challenge (see graphic below) after completing a poll, leaving a blog comment, or purchasing tickets from a website. This is a speed bump to deter bot traffic, by creating tests only humans can pass. If you are interested in additional information regarding CAPTCHA, feel free to visit their website at www.captcha.net.

What does this mean for you? Previously, the only security measure in place was to limit downloads to one-hundred articles per session. Wiley’s new practice will require a user downloading more than twenty-five articles in an active user session, (a session of activity that a user from within your IP range spends on Wiley Online Library) to complete a CAPTCHA challenge, like this one:

Wiley Online Library Captcha

Once the user enters the CAPTCHA information, the download request completes and the user is cleared to continue downloading in increments of twenty-five, up to one hundred in a twenty-four hour period.

Wiley understands and is committed to providing easily accessible information for your patrons. We also realize that this may seem like a hindrance for ease of access to our content. Nevertheless, this has become an essential security measure that we must take to protect both parties. Again, the only patrons affected will be those who try to access more than twenty five articles per session. Upon successful completion of the CAPTCHA test, they will be granted all the access to the content they wish.

If you have any questions, concerns or comments, please send them to EAL@wiley.com.Sincerely,

Wiley Online Library Customer Support
