Here are a few mistakes:
.How many overseers did Solomon appoint for the work of building the temple? (a) Three thousand six hundred (2 Chronicles 2:2) (b) Three thousand three hundred (I Kings 5:16)
How many were the children of Zattu? (a) Nine hundred and forty-five (Ezra 2:8) (b) Eight hundred and forty-five (Nehemiah 7:13)
Who was the father of Shealtiel? (a) Jechoniah (Matthew 1:12) (b) Neri’ (Luke 3:27)
The Gospels say that Jesus cursed a fig tree. Did the tree wither at once? (a) Yes. (Matthew 21:19) (b) No. It withered overnight (Mark II: 20)
I haven't read any of those books so I would not be able to say.
There are no mistakes in the original autographs of the Holy Bible, which we do not have in our possession. What we do have are very good copies of the original Hebrew and Greek Bible. If you know textual studies, then you would be aware of the fact, that there are "errors" in the Bible due to some factors. Some are known as "scribal errors", when the scribe/copyist was in the process of copying the manuscripts, wrote the wrong information down, especially when this information is dictated to them. It is very easy when copying a long list of numbers, and going line by line, for the copyist to write the wrong number in the wrong place. Then we have intentional "errors", when the copyist deliberately made changes to the text, based on their "theology". For example 1 Timothy 3:16, we have the reading of "God was manifest in the flesh", which was changed to "who was manifest in the flesh". This change removes the testimony of the Deity of the Lord Jesus Christ. We know, for example, that the two oldest complete Greek manuscripts of the New Testament, the Codices Vatacanius and Sinaiticus, of the 4th century, were part of those copied at the request of the Emperor Constantine. We also know, that at least two of the copyists were Acacius and Euzoius, both were supporters of the arch heretic, Arius, who denied the Deity of Jesus Christ (see, F Kenyon, Handbook to the Textual Criticism of the New Testament, pp.40-41, sq). The same can be said about the famous Trinitarian text of 1 John 5:7 (KJV/NKJV, etc), which was corrupted at a very early time. On this I have done a very deep study from the Greek grammar of the passage, and shown that the disputed words in verse 7, have to be part of the original text, as removing them cause grammatical problems in the Greek, which is impossible for the Word of God. You can see my study here,

There are scholars who have looked at these so called contradictions and mistakes in both testaments, in great depth, and from what I have read, none of the "problems" like those you mention are errors in any way. Sure there are "paradoxes" in Scripture, but actual contradictions, this is impossible, as the originals are indeed "inspired by God", Who cannot make mistakes.
Dr Gleason Archer has written a wonderful work on "Bible Difficulties", as have many others. It is worthwhile if you look at some of these. Also, some of the older more indepth commentaries deal with textual matters.
