    "en": "Eltjo H. Haselhoff's 2001 Frog Books work — the principal accessible articulation of the residual-anomaly research framework for crop circles by a Dutch physicist who substantially extended the Levengood / BLT methodology. Haselhoff articulates substantive node-bending analysis, substantive electromagnetic-anomaly research, and the broader residual-anomaly framework within which selected formations are argued to exhibit characteristics inconsistent with pure human construction. The work is the principal non-BLT articulation of the residual-anomaly research program."
