I think it will be good for Web editors to create our own page for Newsletter or Annual Report by use pdf file to flipbook page.

Here is example that we used to use for flipbook – http://viewer.zmags.com/publication/85aeccea?viewType=pubPreview#/85aeccea/2

But I think that we can use plugin to do it – https://wordpress.org/plugins/tags/flipbook/
