Abstract
We present a summary update of the QCD spectral sum rule (QSSR) results for the running and {\it perturbative pole} quark masses, the and leptonic decay constants, the heavy-to-light and heavy-to-heavy exclusive transition-form factors. Analytic expressions of these latter quantities are presented, which give a deeper understanding of their - and infinite mass-behaviours. A short comparison of the QSSR results with alternative approaches is done.
