Another approach, which can be used in Blog entries is to take embed it as an Object. For example, the Body for the page http://hoetker.faculty.asau.edu/Research/Research/papers_files/Alliance_experience_and_governance_flexibility.php
is the following line. The first line has nothing to do with this question. The second line provides an easy way for someone to download the document. The third line displays the PDF in a scrollable window. The fourth line is a fallback. This approach doesn’t work as well on mobile devices (at least iThings). There, it displays just the front page of the PDF, but viewers still have access via the Download link. For my likely readership, I’ve decided this is acceptable. For my purposes, I needed to be able to display PDFs on non-Stacks pages. A dedicated PDF viewer stack would probably be the better option if you didn’t have that constraint.
