If you offer books for sale through on-demand printer Blurb, you have to fiddle with the link before you post it.
The normal thing to do is to copy the address in the location bar of your browser and just paste it. Unfortunately, if you do this while looking at your own book on Blurb, you get a link to view your book in your account. Instead of seeing your book, others are prompted to log into Blurb, and then can’t see it because they’re not you.
The link you get while you’re looking at your book will look something like this:
http://www.blurb.com/my/book/detail/394207#store-price
(Go ahead and click it, you’ll see the problem.)
To make a publicly accessible link, take the number out of the link from your account and glue it onto the end of this:
http://www.blurb.com/books/
So for the link above, you’d have:
http://www.blurb.com/books/394207
Now anyone can see the book (in this case, Erik Chevalier‘s Quartu Sant’Elena social club). Yay!
