About Numerical Recipes

Now there are three ways to access Numerical Recipes Electronic from within your browser: New bookreaders Rollover™ and Empanel™, plus the traditional PDF-by-sections interface. Pick the interface that best matches your work style. They all access the same Numerical Recipes Third Edition content, but with slightly different use features. Try one, try all. Subscribers, your same subscription key or institutional subscription will work in each one. For non-subscribers, Rollover and Empanel implement an unlimited free trial of up to 30 pages in any 30 day period, forever. (But we know that you'll soon want to become a subscriber!)

Plus, Rollover and Empanel don't require Adobe Reader® or the FileOpen® plug-in. No installation necessary: They work out-of-the-box with any O/S and browser that is Flash® capable.

Rollover is kinetic, edgy, and very cool. Controls pop up when you mouse-roll over them, otherwise leaving you with a screen-efficient view of just the page. Roll over chapter tabs to expand the list of sections, and go to any in one click. Pages scroll dynamically from the left or right. Click and drag to magnify and move around a page. Advance pages by rollover controls or keyboard arrow keys. Fully linked index is a hierarchical tree. And, you can print pages.

Empanel is predictable and relaxed, with controls that are links in fixed positions. Definitely an interface for the mature crowd, like your NR authors, with no pop-ups or gimmicks. Contents and index open as hierarchical trees, then click through to the desired page. Go to the next or previous page by clicking in the displayed page's margin, or keyboard arrow keys, or go to any page by page number. Breadcrumb tabs show the last 16 pages that you've visited, for easy one-click back-and-forth. Adjust pages to any size. Yes, you can print pages here, too.

Traditional is the interface that you already know. Individual sections download as PDF files, which you read within your browser's Adobe Reader plug-in. Unlike the two new interfaces, Traditional requires the FileOpen plug-in to be installed, and it may not work on some Linux and Macintosh systems. But, for those of you who have gotten used to this interface, we'll continue to support it in its present form.
