<p>This thread on text books sold abroad reminds me of the cold war tactic the USSR used when I was in school. One of the things they did was to have a publishing house funded by their consulate that published a wide assortment of scientific books in English and sold them at ridiculous prices - the Piskunov Differential and Integral Calc book - almost 1,000 pages long, sold for the equivalent of 50 cents - probably the best deal I’ve ever had. </p>
<p>One thing though about the Soviet vs Western books - the same theorem would have different names. After coming to the US, I remember referencing, I think, Ostragradsky’s (sp?) theorem which even my TA hadn’t heard of till he saw the formula.</p>
