After getting the Works of John Wycliffe (AKA Wyclif, AKA Wycliff) bundle as part of a larger package, I noticed that some of these works are in Middle English and are not readable by those not trained in that area of study (see this thread and image of sample text for more on one of the works included in this bundle).
My first concern is that this is nowhere noted on the relevant pages. One would have to click on the sample pages, note the old script and attempt to read the middle English. It should be noted on those pages of that these works are in middle English and modern English speakers may find it difficult to comprehend the text. This is particularly important for the set entitled Select English Works of John Wyclif, which is mostly in middle English, though one would have no reason to conclude that from the title of the set.
Secondly, when I attempted to note this in a review section, I could not log in. Though I was logged in, and the set shows as "grayed out" (already purchased), the bottom section asked me to log in. Clicking that sent me to the Faithlife.com where I was already logged in. Any attempt to get back or forward to the page to review gave the same indication that I needed to log-in first.
