For the past 12 years, the All In Diary has been providing humanitarian practitioners with essential, up-to-date, and succinct guidance for humanitarian workers in a convenient format. Following a revision process carried out on a voluntary basis by practitioners from across the sector over the past year, the sixth edition of the AID is now available. On 22 August, we learned more about this practical resource from its co-founders, as well as from practitioners who are using it and have been contributing to help ensure that the latest edition reflects recent developments in the sector.
