  The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned
observatory of ultra-high-energy particles of cosmic origin, with energies in
excess of 100 PeV. GRAND uses large surface arrays of autonomous
radio-detection units to look for the radio emission from extensive air showers
that are triggered by the interaction of ultra-high-energy cosmic rays, gamma
rays, and neutrinos in the atmosphere or underground. In particular, for
ultra-high-energy neutrinos, the future final phase of GRAND aims to be
sensitive enough to discover them in spite of their plausibly tiny flux.
Presently, three prototype GRAND radio arrays are in operation: GRANDProto300,
in China, GRAND@Auger, in Argentina, and GRAND@Nancay, in France. Their goals
are to field-test the design of the radio-detection units, understand the radio
background to which they are exposed, and develop tools for diagnostic, data
gathering, and data analysis. This list of contributions to the 38th
International Cosmic Ray Conference (ICRC 2023) presents an overview of GRAND,
in its present and future incarnations, and a look at the first data collected
by GRANDProto13, the first phase of GRANDProto300.
