Local observables,nonlocality, and asymptotically separable quantum mechanics

Quantum mechanics is troubled by the problem of nonlocality inherent in the theory. In a series of papers we explore the possibility of an algebraic formulation of quantum mechanics based on local observables which would incorporate nonlocality when small distances are involved but would be separable at large distances. This paper reviews some of the basic ideas and theories developed recently. These include a unified localization scheme, the introduction of local comoving evolution, local comoving observables, and related conservation laws. Technical considerations and mathematical jargon are kept to a minimum to avoid obscuring physical reasoning.An invited paper in honour of David Bohm on the occasion of his 70th birthday.
