•Relatively small number of publications to review •human reach •Not a constraining charge •intrinsic interest of the operator (an OI researcher) in learning about new publications in the OI field •feeding OLBIN itself is not time consuming •Human expertise efficient to estimate the relevance of new astrophysical results from already published OI data (one of the OLBIN criteria) OLBIN evolution Rather NO but open question
