On Tuesday, the 8th of April, the Library Afternoon was held in person and online, in which the presentation of the Jacques-Alain Miller Course "1, 2, 3, 4", Volume 1 was held. The participants were Silvia E. Tendlarz, Enric Berenguer, Ricardo Seldes, and Luis Tudanca; and Virginia Notenson was in charge of coordinating and animating. Papers were presented around the Course, the moment of its appearance in the reopening of the Clinical Section, what Miller had worked on there around the interpretation, transference; anecdotes of the emergence and establishment of the book.
