About the NYPL Digital Yizkor Book Viewer

Blank Screen
The NYPL Digital Yizkor Book Viewer delivers exact facsimiles of the original volumes, presenting the entire book from cover to cover—literally. This means that the first image for any given book will be the front cover (possibly blank), followed by a succession of endpapers, fly-leaves and other blanks, before the substance of the book is finally reached. Don't panic, therefore, if you find yourself confronted with a blank screen; it means only that you are looking at the image of a blank page. Just keep on clicking, as if turning successive pages, and all will be well.

Enlarge Image
All pages containing illustrative matter (about 20% of the pages in these books) may be enlarged for enhanced visibility, often becoming much more vivid than the printed original. A special attraction of the NYPL digital book viewer, the Enlarge Image feature requires installation of the ExpressView browser plug-in, a free download that takes only a few clicks and a few seconds to install. If you do not install ExpressView, you will not be able to enlarge images. By installing the plug-in, however, you will gain access to full-screen enlargements and to the ExpressView toolbar, with the following navigation options:

zoom in Zoom in Click the "+" symbol, then click the point in your image that you want to enlarge. Release mouse to bring image into sharp focus.
