Yes, it is on the website, as well as the app that is used in the meetings.
I always wondered why the WT bothered to publish the Interlinear. At the time, they mostly were publishing books that were intended for offering at the door, ie: for sale, and the Interlinear wasn't something you could sell at the door. Only the JW's would be interested, and only a minority of them at that. The Interlinear had to be a loser money-wise.
It was patterned after Wilson's Diaglott, of course, which had been originally published in the 1800's and was often referenced by the Bible Students.
