| *Both of these citations indicate that the article can be accessed electronically directly from the database by clicking on the HTML or PDF icon. When given both options, PDF is usually the best version to choose. The PDF version of the article is a scanned image of the original including graphs, charts, photographs, and the original page numbers. HTML versions are reformatted. Page numbers will be different from the original, and therefore, difficult to cite. Graphs, charts, and photographs may be missing from the HTML. |
