This information is used to measure the number of visitors to the various sections of our site and improve organization, coverage, system performance or other problem areas. This information is not used for associating search terms or patterns of site navigation with individual users. When search features offer suggested terms, these suggestions are based on aggregated data only. On occasion, NNLM may provide aggregated information to third party entities it contracts with, the National Library of Medicine (NLM) or National Institutes of Health (NIH) for the purposes of research analysis. Aggregated data cannot be linked back to an individual user.
When you visit any web site, it may place a small text file, known as a "cookie," on your computer. The cookie allows the website to "remember" specific information about your visit while you are connected or when you return to that site. The NLM Office of Management and Budget (OMB) Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies allows Federal agencies to use session and persistent cookies.
The cookie makes it easier for you to use the dynamic features of web pages. Cookies from NNLM web pages only collect information about your browser's visit to the site; they do not collect personal information about you. While visiting certain NNLM websites, you may occasionally encounter a web page that automatically employs cookies to make it easier to use the web page’s dynamic features.
NNLM websites may use either single session (temporary) or multi-session (persistent) cookies. Session cookies last only as long as your web browser is open. Once you close your browser, the cookie disappears. Persistent cookies are stored on your computer for longer periods.
- Session Cookies: We use session cookies for technical purposes such as to enable better navigation through our site. The OMB Memo 10-22 Guidance defines our use of session cookies as "Usage Tier 1 – Single Session." This tier encompasses any use of single session web measurement and customization technologies.
- Persistent Cookies: We use persistent cookies to enhance the web experience for our users. Persistent cookies remain on your computer between visits to NNLM until they expire. The OMB Memo 10-22 Guidance defines our use of persistent cookies as "Usage Tier 2 – Multi-session without Personally Identifiable Information (PII)." This tier encompasses any use of multi-session web measurement and customization technologies when no PII is collected.
For example, NNLM uses persistent cookies to avoid repeat submissions to web forms. NNLM may employ persistent cookies in other ways consistent with our mission and the OMB guidelines to analyze use patterns and improve our users' experience on NNLM websites.
How to Opt Out or Disable Cookies
If you do not wish to have session or persistent cookies placed on your computer, you can disable them at any time from your web browser. If you opt out of cookies, you will still have access to all information and resources at NNLM, but you may not be able to use cookie-dependent features.
