The National Digital Repository of Science, Technology, and Innovation (ALICIA) of Peru is in charge of harvesting the scientific production of the universities from their institutional repositories. The aim is to determine and evaluate the availability of resources in the repositories, and if the quality of the metadata harvested by ALICIA has any relation to the metadata of the institutional repositories. To this end, a non-experimental, descriptive, comparative study was carried out after recovering the data from ALICIA, using its API rest and the data from the institutional repositories, and using organic techniques for validating broken links and web scraping, which are then stored in a database on which queries were made using non-SQL statements. There is 97.7% and 95% availability of resources in public and private institutional repositories respectively, and on average, the quality of the metadata describing the resource is between 54% and 57%. It is notable that despite all the documented interventions and the results found, there are still quality problems in the metadata registering process considering that universities are responsible for its publication.
