What is an eBook?
An eBook is a book designed for electronic reading using a computer screen or portable device, such as an iPad.
Are eBooks also available in print?
No. While it is possible to print the books yourself (see below), they are not designed for paper publication.
Can I print my eBooks using my own printer?
The PDF eBooks are printable, however they are not designed to be used in print. Printing is enabled primarily for those who wish to print individual pages (e.g. exercises) to carry into the field. Attempting to print entire eBooks may result in formatting inconsistencies and various technical problems related to the size of the document. While you are welcome to try, we are not able to offer technical support in case you are unsuccessful. If you run into problems, you may try printing via a different PDF reader (see below) or contacting your computer/printer manufacturer for assistance.
May I send a copy of the eBook to a friend or to a commercial printer?
No. Your purchase entitles you to use the eBook yourself. Sharing it with others is in violation of international copyright laws. If multiple people are to use the file, they will each need to purchase a copy.
May I use your eBooks as teaching material for a class?
Yes, however you will need to purchase individual copies for each student.
May I re-sell your eBooks?
You may join our affiliate program and earn a commission on every item you sell. You may not sell the PDF file directly without prior written approval from the author.
I'm having trouble downloading the file(s).
While most users should have no problem downloading the PDF files, they are fairly large and may present challenges for those with slow Internet connections. By default you are granted 5 attempts to download each file. If you exhausted all 5, we recommend that you purchase the CD Delivery option to have the files sent to you on a disc. You only need to add CD Delivery to your cart once. Multiple eBooks can be placed on a single CD.
If you already purchased the eBooks, you may place a separate order just for CD Delivery and send an email to email@example.com asking for your purchases to be mailed to you on a disc.
I'm getting errors when trying to open the file after download.
We test all files by downloading them off the server and making sure they work before releasing them. It is possible the file may have become corrupt during download. Before giving up, please try to download it again to see if the issues persist. If you are still experiencing errors, try one of the following:
- Make sure your reader and/or device are using the latest software versions available from the manufacturer.
- Try a different PDF reader (see suggestions below)
- Try opening the file on a different computer or device to see if the errors are recurring. If not, contact technical support for the device exhibiting errors.

Our eBooks are provided as standard PDF documents that are readable using a variety of devices and applications. Some systems have with built-in support for PDF files. However, reader applications are available for practically any platform. Among the most popular are:
What is your refund policy?
We will only offer refunds if no download attempts were made. Once you click the download link, we have no way to verify whether you downloaded the file successfully and/or removed it from your system and therefore cannot issue refunds.
I'm seeing jumbled fonts when using Preview on Mac OS-X.
This may occur if your Mac has duplicate fonts installed. To resolve font conflicts:
This problem does not affect Adobe Reader.
- Open the "Font Book" application
- Look for fonts with a bullet next to them, indicating a duplicate
- Right-click the font and select "Resolve Duplicates
- Repeat for all fonts that show the bullet
