The first 20 or so pages of this estimated 37 page booklet had me really enthused. The second half, though, got a little too technical for me, but other, smarter writers familiar with LinkedIn will probably love this booklet.
As I realized how eclectic my life has been, I realized I probably would find using LinkedIn to push some of my books,, once I get them written, would be ideal to push on the social site, while others would not, for fear that offense might be taken by those with whom I once worked. Don't get me wrong, I will be saying nothing derogatory about them. Just, some folks abhor their personal statements to be publicized for fear of ridicule.
One point the author makes is the caution against pushing one's book directly, in your face.
Another aspect I liked was the explanation of first, second and third tier associates. Think first, second and third degrees of separation as in Kevin Bacon and you get the idea.
The advice given convinces me that, for many self-publishing, indie, writers, LinkedIn is likely to prove more beneficial to writers than will Twitter or Facebook.
A few case studies to demonstrate what worked and what did not work would certainly improve these instructions.
Thus, I rate How to Use LinkedIn to Sell More Books (Writer's Platform) a Four Star booklet.
