For those (like me) whose eyesight is challenged by the font of the "normal" sized Nestle-Aland 27th ed. Greek New Testament and want more space in the margins to make notes, next month the German Bible Society will be releasing a Wide-Margin Edition Novum Testamentum Graece 27th ed. next month. It will be essentially the same length as the large print edition, but about 3/4 of an inch wider to allow for more room in the margins for notes.
Also available in March will be a Wide-Margin Edition Biblia Hebraica Stuttgartensia 4th ed.
No definitive word yet as to whether there will be a one-volume wide-margin text that combines the two.
