Waheguru, paji,
It's hard to point to one particular resource; it's really more a question of seeking out the actual Truth, beyond the proffered version, in all things. There really is much material available but scattered across the sciences, of anthropology, history, genetics, religious history...
If you go to Israel today, squarely in the Middle East/North Africa (separated by the Suez canal in the the 1860's), and look around you, you feel you are in Europe. The prevailing race, culture and lifestyle is overwhelmingly European. It is no secret that the 'Hebrew' language used today is a modern construction reconstituted from ancient elements of a largely 'dead' language, dreamed up by one individual, a Russian named Ben-Yehudah, together with some other European jews. This language is vastly different from the actual tongue of the African Hebrews in Old Testament times. Similarly, the belief systems of contemporary, Rabbinical Jews is greatly changed from what was the living faith of the ancient residents of that region.
If you're genuinely interested in this, I would point you to the writings of Dr. Ben- Jochannan, also the book "Hebrewisms of West Africa" by Joseph Williams, "African Origins of Modern Judaism" by Jose Malcioln, "From Babylon to Timbuktu" by Rudolph Windsor, as well as recent DNA research concluding that Africans practicing Judaism in the deserts of South Africa are indeed genetic descendants of Biblical priests. This is all just to confirm that the original Israelites were scattered into greater Africa upon the invasions of the Romans, and that the Jews of today who have taken up and redefined that tradition in the absence of the original Israelites, represent a much different tradition than the African Hebrew faith of ancient history.
That modern-day Jews have come to that land largely from Eastern Europe is no great secret.
All of this is just to say that when we compare, for instance, the philosophy of Sikhi with the philosophy of Judaism, it is good to be aware of this distinction. Most Sikhs would be greatly offended if a forum elsewhere might be looking to compare their faith with that of Sikhism and then started out by claiming "Sikhism is a sect of Hinduism", and then began their discussions based on that premise. Truth is Truth.
