All Zentatsu Richard Baker lectures given at the SFZC are now available to listen to and read at Engage Wisdom's website under the moniker The Baker Roshi Audio Archive. That's almost 600 lectures.
They are now linked to from Zentatsu Baker's cuke page.
Cuke Archives provided the funds to have them all digitized in 2013 - as we did with all the Suzuki tapes. In that case it was re-digitized because Charlie Wilson's equipment and methods at EW seemed to me to be superlative. Charlie and I have been in touch many times since then but we were both focused on our own projects and I didn't realize he'd made all of Zentatsu's audio available with what he described as 4th generation AI transcribing. Good move Charlie. - dc
