Yellow-backs

Extracted from the Wikipedia article Yellow-back.
Routledge was one of the first publishers to begin marketing yellow-backs by starting their "Railway Library" in 1848. The series included 1,277 titles, published over 50 years. These mainly consisted of stereotyped reprints of novels originally published as cloth editions. By the late 19th century, yellow-backs included sensational fiction, adventure stories, "educational" manuals, handbooks, and cheap biographies.
