Query: A Bible on sampling theory

This book is a compendium of theoretical results on sampling from finite populations. All other books like Cochran, Kish, Thompson build on it. More modern treatments like Skinner, Holt and Smith; Chambers and Skinner; Korn and Graubard also devote attention to multivariate models like linear or logistic regression. However nothing beats Hansen, Hurwitz and Madow when you need to go through reasonably simple estimators and check that you do understand the proofs.
