About PDF Files
What is a PDF file?
Document Format (PDF) is a file format developed by Adobe Systems,
Inc. and is created using their Adobe Acrobat software. This format allows
files to be viewed online and printed with the exact document layout that
the original author intended, regardless of the platform or browser that
people use. PDF files are used throughout our site, especially in the
MTL section, particularly when reproducing documents that were originally
intended for print publication.
How do I download a PDF file?
Acrobat Reader is required to view a PDF file. This software
is FREE, and is so commonly used that it may already be loaded on your
computer. If you encounter problems while trying to download a PDF file,
you may want to go to the Adobe web site to download the latest version
of Adobe Acrobat Reader. If you are using a relatively new browser
(Netscape or Internet Explorer 4.0 and above), the PDF file should download
directly into your browser. Older versions may prompt you first, asking
whether to save or view the file. If you click on a PDF link and a window
pops up requesting that you select a program with which to view the file,
you probably don't have Adobe Reader loaded on your computer yet.
How do I navigate a PDF file?
To jump from page to page:
Use the scroll bar, or navigate using the page numbers at the bottom
of the screen where it says "1 of 5" or something similar. The
arrow to the right of this area jumps you to the next page, the arrow
to the left of this area jumps you to the previous page.
To jump to a specific numbered page:
- Click the page number box in the status bar at the bottom of the main
window, type the page number, and click "OK" OR
- Choose "View > Go To Page", type the page number, and click "OK" OR
- Drag the scroll box in the vertical scroll bar up and down until the
rectangle to the left of the scroll bar displays the number of the page
to which you want to jump.
- Choose "File > Print".
- Indicate the page range.
- Click "OK" (Windows) or "Print" (Macintosh).
To increase magnification:
In the bottom left corner of the screen you should see a percentage like
"124%". This is the magnification of the page. It can be changed
either by typing a new percentage over it and hitting "enter"
on the keyboard, or by clicking the down arrow to the right of the percentage
and choosing a setting from the list that appears.
Other magnification methods involve using the magnification icon. Select
the magnifying glass symbol (zoom tool) located on the toolbar at the
top of the screen, it is next to the hand tool. Choose one of the following:
- Click on the document page to double the current magnification OR
- Drag the zoom tool to draw a rectangle, called a marquee, around the
area you want to magnify.
To find specific text:
Choose the binoculars ("find") icon from the top of the page.
Enter the text you are searching for, and click "find" or press
the enter key.
