First you will need the full Acrobat software (not simply the Acrobat Reader). (Acrobat is available at a substantially reduced price for educational establishments.)

Acrobat provides three methods for creating PDF files: 

PDF Writer, the quickest and easiest method for creating PDF files 
Acrobat Distiller which uses a more intensive process to optimise compression and functionality 

Acrobat Capture to convert scanned paper documents into PDF pages 
The exact method of creating a PDF file depends on the version of Acrobat which you have installed. 

You may have one or more of the following options: 

An icon on your wordprocessor toolbar . If you click on this a PDF file of your Word document will automatically be created. You will be prompted for filename. 

A 'Print to PDF' option on the File Menu. This will automatically create a PDF as above. 

PDF Writer and/or PDF Distiller listed in the Print dialogue box. 
 

We can also list the book and have them contact you for a hard copy !
