Directory of Open Access Books (DOAB)
Could this be considered for Alma CZ and/or PCI? Thank you!

Important update: DOAB is on Alma CZ but it needs updating: 12,191 portfolios whereas DOAB say they have approx. 19,000 titles.
The directory provides metadata on c. 19,000 OA academic books and chapters. There are well-known University Publishers represented and also some specialist one, especially in African studies, which could help with the diversifying the curriculum.
