Need Help Viewing Our Site?

The NIH Library is making every effort to ensure that the information available on our website is accessible to all users, compliant with Section 508 standards, and compatible with screen readers and other assistive technologies. However, this is an ongoing process and it is possible that some users with disabilities may encounter problems accessing some pages. If you use special adaptive equipment to access the Web and encounter problems when using our site, please let us know.

Please be advised that the actual use of databases, online journals, and online books via the NIH Library website is restricted to NIH staff only due to licensing restrictions. All users can view the lists of resources we make available but the access is restricted. VPN technology is available to NIH users that require access outside of the NIH domain. Please contact the NIH IT Service Desk at 301-496-4357 or https://itservicedesk.nih.gov (an NIH account is required for this site) for more information.

Contact the Information Desk or phone us (301) 496-1080 and provide the address (URL) of the page on which you need assistance, along with a description of the problem.

The NIH Library website is designed so that you can view it using the text style, color and size that you prefer. You may also use the background color that works best for you. To take advantage of these options, you may need to adjust the settings on your browser (software that you use to view websites, e.g. Chrome, Internet Explorer, Safari or FireFox.)

Changing Text Size

Adjustments can be made to the text size by opening the toolbar (often represented by a gear image), then selecting Zoom, and then Zoom In or Zoom Out. Text adjustment can also be competed by clicking the Control and +/- buttons at the same time.

Making Other Browser Adjustments

You can specify the text style and color as well as the background color you prefer when using your web browser. To learn more about how you can make other adjustments, check the Help index of your web browser.

Updating your Browser

Certain web pages are best viewed by using recent versions of Internet browsers. If you are using an older browser version, you may have trouble viewing certain webpages. You can find out what version of your browser you are using by choosing "Help" at the top of your browser and "About (your browser)".
