I have used the original version published decades ago and the design was more user friendly. ie you didn't have to hold it open with both hands. The new version is full of detail and information but would suggest it be bound in a bit larger sized format. This is particularly important when working on a paper on my LT.
If you can find an original copy of Halley's you won't need the new version. The content is and always has been excellent no matter which version you use.
The Halley's Bible is so perfect for me that want to understand more about my study Bible class. All the details of every book of the Bible has a clear explanation and all the characters of the Bible are well introduced.
