NLM Use of Persistent Cookies

The PubMed retrieval system provides a user configuration feature called 'MyNCBI' which employs persistent cookies as an option. The persistent cookie allows users to retain preferences between sessions without the need to sign in to the MyNCBI account each time PubMed is used. The persistent cookie retains preferences such as LinkOut displays, and document delivery services but does not contain any information about the user's searches or navigation through the site. Users may opt out of the persistent cookie selection in their MyNCBI settings at any time.

Many NIH sites are now running customer satisfaction surveys that employ persistent cookies. Participation in this data collection effort is completely voluntary, and failure to respond will in no way affect the visitor's ability to access information. This information will be used by NIH solely for the purpose of improving our public Web sites. More information is available on this use of persistent cookies.
