Publish and Share Files at docs.com
A few weeks ago I introduced Sway and showed how it can be embedded in a web page. I also showed how OneDrive folders can be embedded in a web page.
If you want to embed a single MS Office or PDF document, try docs.com. Microsoft released it to the general public in August 2015, and I think it is worth a look.
Docs.com
Go to Docs.com sign in with your microsoft account (hotmail, live.com, outlook.com) publish your document, and start sharing. Here is Microsoft’s introduction to docs.com (an embedded Powerpoint online show)
Health warning – if you publish documents at docs.com, they are public; they can be found and viewed by anyone, and, depending on the license you select when publishing, can be amended and redistributed by anyone, without attribution of your work.
