I have not read any of the books, but the authors are all well-respected scholars in their fields. A few of them may be a little on the older side, such as the Egyptian book by Gardiner (he died in the 60s, so the book won't include anything discovered in the last 50 years), but authors such as Norm Hammond (who I am personally acquainted with) and HWF Saggs and Glenn Markoe are all solid academic scholars. I would feel confident in citing any of these works based on the name recognition of the scholars alone.
