"Bulletin of the Department of Visual Instruction", 1930 December

As researchers request materials, a review of the documents will take place. Staff will remove any documents with social security numbers, employee numbers or other sensitive identifying information. Any document found including this information is closed for 90 years from date of creation, or until verifiable proof of a person’s death is given. After these documents are removed the folder will be available for research. In some cases, items may be photocopied and redacted. The redacted copy will then be placed in the publicly available folder. All other materials in a folder will be freely available for immediate use and will be marked as having been reviewed by Special Collections staff. After folders have been reviewed using these procedures and the confidential materials have been removed, the restriction shall be lifted..
