2. Identify the materials you need: Once you have a research topic in mind, you should identify the specific materials you need to consult in the Vatican Library’s collections. This will help you to provide detailed information about your research needs when submitting your request for access.
3. Submit a written request: To request access to the Vatican Library, you will need to submit a written request at least six months in advance of your planned visit. The request should include your research topic, the specific materials you need to consult, and the dates of your planned visit.
