The following information is automatically collected: (1) the IP address/hostname used to access our website, (2) date of the visit, and (3) the pages that were visited. The IP address under (1) is used only to generate an approximate count of visits. Most IP addresses are allocated dynamically or configured in such a way that they are not traceable to individual users, and at any rate we do not use this for any other purpose. No information such as names, computer characteristics, or computer content is collected. We do not sell or distribute any web visitor information.
Visitors may provide additional information on a voluntary basis. For example, signing up for our email list or our mailing list requires an email address and/or additional name and address information. Requests for publications also require the customary name and mailing information. This information is maintained in secure databases only for the stated purpose and is not used in any other way. We do not sell or distribute any email list, mailing list, or publications request information.
Our Publications Search system uses "cookies." A cookie is a small file stored on your computer, and in our implementation, contains a single, randomly generated number. It allows the web server to keep track of publication requests as a visitor conducts different searches and/or surfs different pages. The cookie expires, that is, becomes inactive after a brief period of time and does *not* store or transmit any information about the visitor or visitor's computer.
