Information for Readers Geological Materials Research (GMR) papers are prepared in portable document format (pdf) and can be viewed with the free Adobe Acrobat Reader (4.0 or later).  If you do not have a copy of Acrobat Reader on your computer, you should download one from the Adobe Systems site before trying to read GMR papers. It is recommended that you use the latest version (5.0) of Acrobat Reader if possible. However, you can read the titles and abstracts of GMR papers with your web browser, even if you don't have a copy of Acrobat Reader. To view a complete GMR paper, click on the PDF button at the bottom of the Abstract page.  The result will depend on your web browser configuration.  (1) If you have the Acrobat Reader Plug-In installed in your web browser, the pdf document will open in a new browser window.  Because papers with lots of images can be large, it may take a while for the pdf file to open if your internet connection is slow.  If the time it takes to load a pdf file is noticeably long, we recommend that you save a copy of the article to your hard disk, after it is loaded by your browser, and then open it directly with Acrobat Reader.  This will be especially useful for larger papers with linked figures (such as movies) or other files in addition to the pdf file, which contains only text and simple graphics.  (2) If you don't have the Acrobat Reader Plug-In installed in your browser, then your browser will try to copy the pdf file directly to your hard disk, asking you where to save it.  In either case, if the paper contains links to movies or other files, you may still wish to be connected to the web when reading. Using the Acrobat Reader Papers in GMR are optimized for viewing and reading onscreen, although text and static graphic can be printed for offscreen reading. If you read a paper onscreen, you will be able to take advantage of the Acrobat navigation tools. To quickly move from text to figures or tables and back again, readers should use the bookmarks, hyperlinks, and Acrobat Reader navigation buttons.  When the paper is opened, a list of "bookmarks" should appear to the left of the text.  Selecting a bookmark will change the view quickly to the selected part of the text, a figure, or a table. The triangular "next page" and "previous page" buttons move the view from page to page.  The triangular buttons with a vertical line move the view to the beginning or end of the document.  The arrow buttons move the view to your previous location in the document.  Where figures or tables are mentioned in the text, a mouse click on the word "Figure" or "Table" will bring the figure into view.  Click on the arrow button to return to the page you were reading. You may find the magnifier button useful for looking at the details of figures.  Try out the buttons and you will see how easily and quickly you can move around a pdf document.  Printing a Paper The pdf format used for text and static figures in GMR will print very nicely at high resolution on postscript printers. Readers may print GMR articles for their own use if they wish.  GMR articles may be duplicated freely for educational purposes.  However, GMR articles may not be duplicated for sale or profit of any kind without the written permission of the Mineralogical Society of America.
