Pay attention to the number of pages. This is the only indicator (not really visible) that will confirm if it is a full version or not. In version "Pocket Book" that we had ordered, we found that the volume size does not fit that was expected. Looking in the first pages, it is written that for easy reading, not really interested young people, the work was deliberately shortened (about 2/3) because it is a way to get them gradually to reading. A selection of the most important passages are retained. Now for everyone to see.
