I have been studying about the Chebotarev Density Theorem and have been hunting for the following paper of Lagarias and Odlyzko for quite a while:
Effective versions of the Chebotarev density theorem, J. C. Lagarias and A. M. Odlyzko, pp. 409-464 in Algebraic Number Fields, A. Frohlich (ed.), Academic Press, 1977.
I tried looking for the paper as well as for the book itself however the only results I get are other papers citing the above reference. I would be really grateful if someone could post a link to the paper, as I am really stuck without it.
