Google EBooks---- SDC Publications
Welcome to SolidWorks forums Neko.
I don't think you can get them without going for the training but you can also check SolidWorks Books and Manuals in SolidWorks online Store
You might also find this post helpful for your future reference.
As Matt said, you can pick them up from eBay sometimes.
I buy the books directly from our vendors.
Try to buy the books there.
I only have the number for the German version.
