Don't forget there are actually LOTS of Antarctic meteorites! I'd say those figures are pretty good considering most (though not all) NWA's are usually quite weathered, and off a bit less science value than the pristine ones collected on ice... That's probably why the statistics show non NWA's are under represented in literature. I doubt it's because NWA's are too expensive to work on.

Far more important research results have been coming from the Antarctic meteorites than from hot desert meteorites. I did a quick count of meteorites used in studies published in both major meteoritics and cosmochemistry journals in 2006. Each tally means one meteorite mentioned in one paper (if the same meteorite is mentioned in 6 papers, it counts for 6). Here are the results: Geochimica et Cosmochimica Acta: Saharan+Oman meteorites: 22 Antarctic meteorites: 62 Non-Antarctic/non-saharan meteorites: 109 plus one paper with 50. In Meteoritics and Planetary Science: Saharan+Oman meteorites: 10 Antarctic meteorites: 80 plus one paper with many. Non-Antarctic/non-saharan meteorites: 106 plus one paper with many. The real question is, why are hot desert meteorites so miserably UNDER-represented in the literature. I think there are several answers, and there are probably many more: 1) Falls are often the most valuable samples for research due to lack of weathering. 2) Research specimens of hot desert meteorites tend to be very small. 3) Hot desert meteorite are not well distributed in the research collections of the world (especially in the US), and are much harder for scientists to obtain. 4) All of the major Antarctic collections are well curated and have formal procedures in place for obtaining samples. 5) Hot desert meteorite collections are useless for the study of irons.
