I am looking at
but only volume one has pages for preview. Can preview pages be added for more than 1 out of 100 books so I we can have a better idea of the series content and approach? Thanks.
This is where Amazon's previews prove useful.
In the "New to you" section, you can hover over any resource to get more details. Do that, then click on the resource title in the popup (CTRL+click if you want to open in a new tab).
You'll then get a product page for that resource. At the top of that page, under the cover image, you'll see a link that says "See Inside". That will give you a preview of the book in Logos format.
