How do I (with Logos 9) put my library into categories. I own a huge number of Logos eBooks, but as of now, the are somewhat like a big room with thousands of books strewn around in random order. I wish to put all my Bibles in a Bibles Group (with subcategories for Greek, Hebrew, Spanish, English, etc.) Bible commentaries in a commentary group (& sub group that by OT & NT, & further to things like Pauline epistles, General Epistles), my lexicons in a Lexicon Group, my Civil War books in a History group, the Loeb Classics in a Loeb Group, etc. BTW, this is so easy with Accordance!
