These reports used to be secret but there was a law passed in 2018 requiring this website and that the reports be published for the public to view:
"In 2018, Congress passed a law directing the creation of this site and ending the legal requirement prohibiting CRS from providing its products to the public. In response, the Library immediately started work to ensure all products required under this new law would be available at launch, as well as add as many additional products as possible (see the FAQ for details and a timeline on the distribution of additional products)."
