The characteristics of the Jefferson LAB electron beam, together with those of the experimental equipments, offer a unique opportunity to study hypernuclear spectroscopy via electromagnetic induced reactions. Experiment 94-107 started a systematic study on 1p-shell targets, C-12, Be-9 and O-16. We present the results from C-12, O-16 and very preliminary results from Be-9. For 12 C for the first time measurable strength in the core-excited part of the spectrum between the ground state and the p L state was shown in (12)(Lambda) B for the first time. A high-quality 16(Lambda)N spectrum was produced for the first time with sub-MeV Energy resolution. A very precise B L value for N-16(Lambda), calibrated against the elementary (e, e'K+) reaction on hydrogen, has also been obtained. Final data on 9 Be will be available soon. The missing energy resolution is the best ever obtained in hypernuclear production experiments.
