Thanks again for your report and your patience as we worked through this. The way this used to work was that we would save the detail page URL supplied by the Amazon API unconditionally for books read and written. As you've seen, the URL includes some query string parameters that make it quite long and unattractive on the PDF version of your CV.
I have updated our code to remove the query string parameters prior to saving the URL as they are not needed for the hyperlink to work nor are they needed by us. This update will be pushed to production shortly. I have also updated the hyperlinks for the two books you wrote to use the shorter URL.
Note to Others: All other CVs have been left untouched and use the longer URL. If you wish to see the shorter URL, you can search for and update each of the books listed in your CV. If there is sufficient demand, we will look into an automated way to update everyone.
