Buy the books!
In the U.S. and Europe, Knowing Place and Knowing Past are available through Amazon.
In the U.S. they can also be purchased online through CreateSpace (click here).
You can also buy Knowing Place directly through the Swedish publisher’s widget (click here, then 1. click on book icon, 2. click on shopping cart icon at bottom, 3. write in number of books, 4. click on triangle at bottom right, 5. fill in required information and continue clicking on triangle arrow on the right.) However, it is usually cheaper through Amazon or web bookstores.
