Display/Browser Support

Why don’t I see more of the page?
How much of the page you see depends on your monitor screen resolution. We recommend viewing ANNALS on tablets and PCs at a screen resolution of no less than 1024 x 768. 

Which browsers and platforms are supported? Which are not supported?
ANNALS currently supports most recent releases of the following browsers: Microsoft Internet Explorer 8 and later, Microsoft Edge, Mozilla Firefox, Apple Safari, and Google Chrome on Windows and Mac operating systems. 

Viewing on Mobile Devices

If you are accessing ANNALS on a web-capable mobile device (such as a smartphone or tablet), display of most pages and content will automatically be optimized for mobile viewing.

What are the technical requirements for viewing on mobile devices?

  • ANNALS will accommodate a minimum screen resolution of 320 x 240 pixels.
  • Supported mobile operating systems include, but are not limited to: iOS 2.0 and above, Android 3.0 and above, Blackberry OS 7.0 and above.
  • The leading products from the top mobile manufacturers in the United States by web usage are supported.

What pages are optimized for viewing with mobile devices?

  • Most mobile browsers are limited in their ability to transmit large files quickly, so only the most essential information is included in the mobile optimized view of ANNALS. Search and navigation are simplified as well, to better suit the small mobile screen. Mobile site users have full access to ANNALS's powerful semantic indexed search.
  • Mobile optimized pages include
    • Full journal issues and articles and textbook chapters (including figures, tables, and references) as well as abstract pages if the user is not signed in
    • The home page, Current Issue, Past Issues, Topics, and Search pages
    • Share and Email features
  • Pages that are not optimized for viewing with mobile devices (display remains as is when viewing on a desktop or laptop) include Self-Assessment/CME content, subscription/store, some multimedia, and informational pages.
