You don't even need a scholarly article as proof that there can be errors in a bible. All you need is a spare Bible and a permanent marker. Change one letter in the text, and there is an error. There you have it. Physical proof that there can be errors in a Bible. No matter what proof you show that a Bible actually had a typo, one could just say that the mistake was made on purpose to disprove the inerrancy of the Bible. You could go to the museums that house one of the famous Bibles with an error. You could also go to the museum's websites and search the archives. But one could say the same of those Bibles, that the errors were made on purpose.
One also doesn't need to look any further than their own Bible to see errors from original manuscripts. 1 Samuel 17 says that David killed Goliath, but 2 Samuel 21:19 says that Elhanan killed Goliath.
Again there was war at Gob with the Philistines, where Elhanan the son of Jaare-Oregim the Bethlehemite killed the [brother of] Goliath the Gittite, the shaft of whose spear was like a weaver’s beam.
The New King James Version. (1982). (2 Sa 21:19). Nashville: Thomas Nelson.
A footnote from the KJV (which also italicizes "the brother of") says that "the brother of" was supplied from 1 Chr. 20:5. LEB, which was made to be close to interlinear, omits the additional "the brother of" placing it in a footnote saying that he likely killed the brother of Goliath given the verses I've already shown. If you really wanted to, you could also go to the Hebrew manuscripts and see that they don't have "the brother of" (or else they also have it supplied in brackets) in their text. I have an info-graphic explaining how that error likely happened.
Moreover, if there were no errors in Bible anywhere along the line, then how could there be verses that are included in some English Bible verses and not in others? How could there be translations that say totally opposite things such as how the Jehovah's Witness Bibles say that Jesus is not God while translations such as KJV say that He is. They both can't be right. One or the other must contain some kind of error.
Of course, these misprints don't mean that the Bible is untrustworthy. If one can believe that God prevents all typos when someone is writing scripture, then it shouldn't be hard to believe that God preserves the Scripture in light of misprints, textual errors, and mistranslated.
