Below is a list of sources that I have found online that cover this topic in depth, more to be added soon. If there is anything I have left out, please provide a link in the comments section.

There is a lengthy series by Rabbi Bazak from yeshivat har etzion.
In particular there are chapters on verses possibly added later than Moses
http://etzion.org.il/vbm/english/archive/tanakh/03a-tanakh.htm
http://etzion.org.il/vbm/english/archive/tanakh/03b-tanakh.htm
http://etzion.org.il/vbm/english/archive/tanakh/03c-tanakh.htm
http://etzion.org.il/vbm/english/archive/tanakh/03d-tanakh.htm
other chapters (ie change 03 to earlier or later) deal with possible contradictions in the Torah, archaeology etc
