#### Hard copies

The best way to use the open course book is to download the .pdf file to your laptop or tablet. Then you can use all the internal links to interactive material. You do NOT need to buy a printed copy. This calculus "open book" is now part of the Open Textbook initiative that is meant to save you money. You can use the usual .pdf tools to highlight or annotate the file, just as you would annotate a printed copy.

You can optionally buy a printed paper copy of this material from Copiesmart on University Boulevard. The cost after tax will be \$25. Be aware, though, that the printed copy will not have the full functionality of the .pdf file version.

Address: Copiesmart, #103 5728 University Blvd. Tel: 604-222-3189, 604-222-3194. Call first to see whether they are in stock, or need to have more printed. Copies should be available from the morning of Thursday Sept 6.
