I have discovered that the current practice Logos has adopted regarding Logos Research Editions is to place this critically useful information under a Learn More link.
I found this to be so by chance when investigating a certain resource: A Historical Theology of the Hebrew Bible by Konrad Schmid.
I find this to be a little confusing as my first impression was that it was a Readers Edition this feature should be rethought as it is not the most straight forward way to convey this information.
Whether an edition is a Readers edition or a Research edition or an E-book should be instantly apparent as it may determine whether or not the resource will be purchased.
