Evangelical Textual Criticism: How Bad is Wikipedia? Codex Alexandrinus as a Test Case
Anyway, I was checking the wikipedia article for Codex Alexandrinus. That is over 7,000 words and 94 notes. It is full of information, and probably would give readers a reasonable idea of the manuscript. And the problems are sometimes subtle. Like the fact that a large proportion of the scholarship cited is from the 1800s (that doesn't make it wrong, but it does make it dated). Practically every sentence is poorly expressed (and that comes from an Australian). Look at that first note to Greek Bible! But I found a load of problems. (I know it can change all the time so I'll include the relevant bits here.)
Some of the pitfalls apply to a lot of the posting at Wiki.
