Lending libraries occasionally make mistakes when scanning articles, including blank or irrelevant pages. If there are detailed illustrations in your article the lending library may scan those pages in twice; once for the text, and once in color or grayscale to make the illustrations clear. Pages missed in the first scan may be included twice, located in the wrong place, or appended to the end of the article. Scan are created by people, often students, and are thus subject to human error. 

Please check the document thoroughly - apparently missing pages may be elsewhere in the document.

If there are missing pages or illegible scans or any other problems with your article, please respond to the delivery notification email of the request so that we can re-order the affected pages.
