The National Library of Medicine (NLM) offers this website as a public service. We do not collect any personally identifiable information (PII) about you when you visit our Web sites, unless you decide to provide us with such information. We collect information about your visit to our website to help us better understand how the public uses the site and how to make it more useful. NLM never collects information for commercial purposes or for any purpose that is not related to the functions of NLM.
Type of Information Collected
When you visit any website, some information about your visit is collected. NLM collects and automatically stores this information about your visit:
- Internet address and the domain from which you are visiting the NLM website
- Information about the operating system and browser used
- Date and time of your visit
- Pages Visited
- Internet address of the website that connected you to the NLM site
- Words sought
This information is used to measure the number of visitors to the different sections of our site and to improve the organization, coverage, system performance or problem areas. This information is not used to associate search terms or site navigation patterns with individual users. When search functions can suggest terms, these suggestions are based only on aggregate data. NLM periodically deletes Web logs. In some cases, NLM may provide aggregated information to contracted third parties for research analysis. The aggregate data can not be linked back to an individual user.
If your electronic health record (EMR), health records (PHR) or other system links you to MedlinePlus, its diagnostic codes or other information such as medications or procedures, you are sent to our site to link it to you with most information relevant. No identifiable information is collected in this process. We may review the information in order to improve our site and better meet the needs of users, but this information is reviewed at the aggregate level.
When you visit any website, you can 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 online or when you return to that site. The note from the Office of Management and Budget (MMO) M-10-22, Guide for Online Use of Web Measures and Customization Technologies (PDF *, 1.03MB), 6/25/2010, Enables federal agencies Use persistent and session cookies as Defined below.
NLM Web sites may use single (temporary) or multiple (persistent) session cookies. Session cookies only last while your 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, for example, to allow better navigation through our site. WMO note 10-22 defines the use of session cookies as “Usage Level 1 – Single Session”. This covers any use of single session metering and personalization technologies.
Persistent Cookies: NLM uses persistent cookies to improve our users’ web experience. Persistent cookies remain on your computer on your NLM visits until they expire. The WB 10-22 memo defines the use of persistent cookies as “Usage Level 2 – Multiple Session Without Personally Identifiable Information (PII)”. This level covers any use of multisession personalization and measurement technologies in which PII is not compiled.
For example, NLM uses persistent cookies to enhance the function of the PubMed retrieval system called “MyNCBI”. The persistent cookie preserves user preferences such as filters for results, samples of LinkOut, links to institutional icons, information delivery services, etc.
