The Golden Field Guides are a series of larger pocket-sized books that were created by Western Publishing and published under their "Golden Press" line (mostly used for children's books at the time), as a related series to the Golden Guides.
Edited by Herbert Zim and Vera Webster, the books were written by experts in their field and illustrated with a simple straightforward style.
The series, updated, was relaunched in 2001 as "Golden Field Guides by St. Martin's Press".
Certain titles have been discontinued, such as the Amphibians of North America and Families of Birds books.
There were some other "Golden Guides" issued but not normally considered part of the regular series.
