Certainly a valuable resource, but the format leaves a lot to be desired. In a printed book it makes sense to cram in as much text per page as you can, but it's hard to read. In the digital format Logos missed the opportunity to enhance readability by breaking up some of the lines and differentiating formatting. We have here a nice replica of the print edition's gargantuan paragraphs, but there are much more readable versions of this public domain resource available.

As great as it is to have this material in digital form, the format is ultimately unhelpful in my opinion. The marginal notes that are a hallmark of Ørberg's texts are put in as footnotes. That makes sense from a coding standpoint, but you lose the easy accessibility of the explanatory pictures and crucial grammatical information. This is also a problem in Exercitia Latina, where word banks now appear after the exercises, making it difficult to see the options, though it is nice to have fillable forms. The hyperlinked index in Familia Romana is nice, but the rest of the texts actually seem to lose utility by virtue of being digitized. The biblical texts in Epitome Historiae Sacrae don't interact with the rest of the Logos ecosystem, and the heavy use of marginal notes in that text makes reading it with popup footnotes a real chore. In browsing, I found a few spots where the text employs two columns, which would have been ideal for displaying marginal notes. I'd recommend this for all the text!
