I believe that every scholar who is interested in some problem of a general nature, but does not write in one of the "major" scholarly languages, is bur-dened with a certain feeling of stifling isolation because of the difficulties he has in communicating his findings and ideas to a larger group of in-terested colleagues. I therefore welcomed the suggestion of Professors Gil-bert White of Chicago and Allan Pred of Berkeley that my 1953 monograph on the diffusion of innovations be translated. Simultaneously, however, I felt a natural hesitation about seeing the book reissued without alterations and additions.
