References for IQ gaps in other nations

I continue my Herculean task to check all our references. Two questions for the cognoscenti below. Please help.  2 July 2005 13:38 (UTC)

European IQ
The third paragraph of 2.3 refers to a web page (it's also a boo-boo external link and needs to die). The web page itself lists
 Buj, V., 1981, Average IQ values in various European countries, Personality and Individual Differences, 2, 168-169
Alexopoulos, D.S., 1997, Urban vs rural residence and IQ. Psychological Reports, 80, 851-860
Lynn R. and Vanhanen T., 2002, IQ and the Wealth of Nations, Westport, CT: Praeger. [Online Table]
Demetriou, A., 2005, The architecture, dynamics, and development of mental processing: Greek, Chinese, or Universal?, Intelligence, 33, 109-141
I would be happy to link to any of these primary sources instead, and I think Buj is the correct one, right? So I would like the footnote to read: 
Buj (1981), some of the data can be found at Greek IQ
Any objections? 2 July 2005 13:38 (UTC)
15 point catholic/protestant gap
In the same section
The difference between the neighboring white Protestants and Catholics in Northern Ireland is as large as the differences between whites and blacks in the U.S.[6]
Now, footnote [6] is again an external link (to Myth: some ethnic groups have genetically inferior IQ's (sic)), but that web page is much harder to navigate. What I am looking for is a reference for the catholic/protestant gap. A POV web page isn't good enough for that. 2 July 2005 13:38 (UTC)
