The Dewey Decimal Classification (DDC), colloquially the Dewey Decimal System, is a proprietary library classification system first published in the United States by Melvil Dewey in 1876. Originally described in a four-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last over 100 years. Once common, only about one in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration.

Covered Bridges Today is a non-fiction book on the architecture of covered bridges in the United States. The book was written by Brenda Krekeler and published by Daring Books in 1989. Covered Bridges Today is a frequently cited source on the topic of covered bridges and serves as a record of numerous covered bridges that have since been dismantled or demolished since the book's publication. Krekeler's text includes 412 covered bridges in fourteen states with a complete record of all 142 covered bridges in Ohio during its writing in 1986 and 1987. The work has been utilized in numerous citations by later publications including Historic American Engineering Record surveys and New England's Covered Bridges: A Complete Guide, Indiana Covered Bridges and Covered Bridges in Virginia.
