Access to literature is crucial to create good professionals, but the US blockade specifically bans the sale of books to Cuba. The Havana University library lacks the fundamental books needed in the formation of human resources. Cymru Cuba is proud to support a project to send books to Havana University. Cymru Cuba has sponsored the transportation of books from Cardiff University to Havana University. Cardiff University is part of a successful project between the Welsh Assembly Governments education department and the ministry of higher education in Cuba. This donation is from all the professors at Cardiff Uni organized by Dr. Colin Berry and Juan Alexander Padron (Cuban PhD student at Cardiff Uni supported by the Royal Society), whom had been able to collect more than 300 up to date science books in topics like Chemistry, Biochemistry, Mathematics, Biology and related sciences. All the donated books contain an insert highlighting that they are part of a donation from the people of Wales to improve Cuba University system.
