All I can say is that the pair of books that LEDAS sent me from Novosibirsk look impressive. In the case of The PLM Enclopedia, hardcover, glossy paper, full color, and full of Cyrillic characters. The UPS delivery man was also impressed: How much had it cost to send two heavy books all the way from Russia, he wondered.
For an English online version of The PLM Enclopedia, see www.plmpedia.org
For Introduction to Mathematical Background of CAD/CAM/CAE/PLM, well I suppose the Russians would prefer to keep their tactical advantage by not translating their math into other languages.
