In discussing my question Does any research/study exist on what makes an interactive document better from a user experience perspective? an interesting argument has arisen that using a website is a better approach for creating an interactive document, as opposed to creating an interactive PDF for example.
To my mind, an interactive document is not the same as a website. Sure, they can be designed to be very similar and can share some of the same attributes and goals, but a single document that is entirely portable and can be viewed on any computer regardless of whether it is online or not will meet the needs of many situations that a website cannot do in the same way or with the same ease.
Some examples I can think of where creating interactive documents (such as PDF) may be preferable:
The above are only some examples.
I know an argument could be put forward that you can create a website that is stored locally (and not in fact published online at all), but the portability of these is questionable. For example, one can email a single PDF while one cannot email a website. Sure, you could compress the site (e.g. into .zip format) but many email gateways will block compressed archives.
So, I am wondering what research or studies exist relating to the comparison of interactive documents with websites from a user experience perspective, and in what situation(s) should one choose either option over the other to ensure the best experience for users.
This question is a false dichotomy from implementation point of view and the UX questions are unrelated to which implementation is chosen (if done well), so it is very unlikely that any such research exists:
