In addition to information collected automatically, we use cookies, which are small pieces of information sent to your browser by a website that you visit. Cookies are used to track usage patterns, traffic trends, and customer behavior, as well as to record other information from the website. When you register on the website, cookies also allow us to save information so that you will not have to re-enter it the next time you visit. Many content adjustments and customer service improvements are made based on the data derived from cookies. The Smithsonian uses third-party research companies that may use information about your visit to this website or other websites in order to provide quantitative analysis about our audience. Information that we collect from cookies will not be used to create profiles of users and will only be used in aggregate form. The data is retained for as long as necessary to support the mission of Smithsonian websites. You may set your browser to refuse cookies from any website that you visit. If you choose to do so, you may still gain access to most of the Smithsonian's websites, but you may not be able to conduct certain types of transactions (such as shopping) or take advantage of some of the interactive elements offered.

Additionally, the Smithsonian employs outside companies to provide marketing services on our behalf. With our approval, these third parties also may place cookies during your visit. These third-party companies will have access to the information needed to perform their functions but cannot use that information for any other purpose. They will not collect or have access to personally identifiable information. These third-party companies only collect information about your visit or transaction, such as the URLs which lead you to, around, and from our site, pages visited, the product(s) purchased, and the amount spent.

The Smithsonian also uses outside advertising and analytic companies to serve ads on and about our website. These companies may use information about your visit to this website or other websites in order to provide relevant advertisements and offers that may be of interest to you on this website and on other websites you may visit later.

Web Beacons and Pixels

The Smithsonian also collects non-personally identifiable information through the use of tracking pixels that appear on our pages. A tracking pixel is a transparent graphic image (usually 1 pixel x 1 pixel or Javascript tag) that is placed on a web page and, in combination with a cookie, allows us to collect information regarding the use of the web page that contains the tracking pixel.

We use tracking pixels to trigger ads on participating websites based on activity tracked from the browser on a device used to visit Smithsonian Websites. We also use them to tell when an advertisement we run on another website has been clicked on by Smithsonian Website visitors, and use that information to judge which advertisements are more appealing to users. Pixels can also be used for third party web analytics.
