I find sample pages important in many cases when deciding on buying a book.
Logos often has no sample pages, and often when they do, the sample are not representative of the book.
For example, on a commentary, the sample pages should show how the author deals with the text. The sample pages almost always are from the introduction which tell the potential reader nothing about whether the author's comments are helpful.
Recently, Logos has published a number of books containing essays. Here you need to at least list the titles of the essays, so one can judge if the topics are relevant to our line of studies.
I buy a lot of books, but I have passed on a lot of these where I'm not sure if the book is what I need.
