Annotate PDF documents in Adobe Reader
 
To view, print and annotate your article you will need Adobe Reader version 7 (or higher). This program is freely available for a whole series of platforms that include PC, Mac, and UNIX and can be downloaded from http://www.adobe.com/products/acrobat/readstep2.html.
 
To make annotations in the PDF file, go to the main Adobe toolbar and change the cursor from a hand symbol to the normal cursor by clicking on the ‘Select’ button in the menu bar at the top. When you open the PDF file using Adobe Reader, the Commenting toolbar should be displayed automatically; if not, click on ‘Tools’, select ‘Commenting’ (or ‘Comment & Markup’), then click on ‘Commenting toolbar’ (or Show Comment & Markup toolbar in Acrobat Reader 8, or Show Commenting bar on the Mac). If these options are not available in your Adobe Reader menus then it is possible that your Adobe version is lower than version 7 or the PDF has not been prepared properly.
 
PDF ANNOTATIONS (Adobe Reader version 9)
The default for the Commenting toolbar is set to ‘off’ in version 9. To change this setting select ‘Edit | Preferences’, then ‘Documents’ (at left under ‘Categories’), then select the option ‘Never’ for ‘PDF/A View Mode’ – see next page (the Commenting toolbar is the same as in version 8).
