1. H.J. Lipkin: Phys. Rep.C8, 173 (1973). The quark model and many of its applications are discussed there, except elastic nucleon form factors; ibid. in: High-energy physics with polarized beams and polarized targets, eds. C. Joseph, J. Soffer, EXS 38. Basel: Birkhäuser (1981)
2. R.G. Sachs: Phys. Rev.126, 2256 (1962); L. N. Hand, D.G. Miller, R. Wilson: Rev. Mod. Phys.35, 335 (1963). The last mentioned authors drew attention to the consistency ofG E,p =μ p -1 G M,p with data then available forQ 2 less than 2 (GeV/c)2, which was characterized as “an amusing relation for which we can find no meaning”. Several advantages of using Sachs form factors, calledG E ,G M there, rather than using Dirac and Pauli form factors, were pointed out. In retrospect, one may add to their arguments the lack of meaning of distinguishing a bare nucleon (Dirac fermion) and a dressed nucleon (carrying a magnetic moment which is the sum of a Dirac moment and a Pauli moment) in the quark model [13]. This distinction has had strong impact on this subject (and on other ones as well). See e.g. J. Bernstein, M.L. Goldberger: Rev. Mod. Phys.30, 465 (1958) and [5–8] below
3. S. Galster et al.: Nucl Phys.B32, 221 (1971), Historically also the question of nonvanishingG E,n (Q 2) has been controversial, see e.g. L.I. Schiff: Rev. Mod. Phys.30, 462 (1958)
