The $^9$Be$$(\gamma,n)^8$$Be reaction is enhanced by a near threshold $1/2^+$ state. Contradictions between existing measurements of this reaction cross-section affect calculations of astrophysical r-process yields, dark matter detector calibrations, and the theory of the nuclear structure of $^9$Be. Select well-documented radioisotope $^9$Be$$(\gamma,n)$$ source yield measurements have been reanalyzed, providing a set of high-accuracy independently measured cross sections. A Breit-Wigner fit of these corrected measurements yields $$E_R=1738.8\pm1.9$$ keV, $$\Gamma_\gamma=0.771\pm0.021$$ eV, and $$\Gamma_n=268\pm15$$ keV for the $1/2^+$ state. A virtual $1/2^+$ state is excluded with 99.3\% confidence.
