I purchased a quad, and am now in the process of transferring all my markings from the old to the new. I know that some, even general authorities, advocate not transferring and just marking as you read the new. I'm not of that school of thought. I transfer and refine my markings each time. The above triple was purchased in 1985 when I was called to be a Gospel Doctrine teacher and I gave up my beloved triple that I had used as a missionary.
I enjoy the process of marking a new set of scriptures as it gives me a chance to see again forgotten treasures, change markings to meet my evolving system, and wonder why the heck I ever marked that one! One change I'm making is that I'm no longer drawing a box around a passage and coloring it in completely. I'm simply underlining the passage.
I love the scriptures, they truly are a lamp unto my feet. Psalm 119:105
