The Chicago Manual of Style recommends against citing secondary sources. A secondary source (also known as an indirect source) is a source quoted within another source. In rare cases, it is not possible to cite the original source. For example, if the source is out of print and not accessible, or is written in a language other than one you are able to read, you may need to cite a secondary source.
