Second edition with corrections, new prefaces, a redesigned flow chart, and updates to the original text based on new information that has come to light over the past decade.

This manual is designed for professional conservators, librarians, private collectors, and researchers who want practical, contemporary insight into preserving architectural plans and drawings. The authors provide detailed methods for identifying architectural photoreproductions based on visual examination. The manual discusses twelve distinct processes and offers additional information on several other methods commonly used in North American architectural practice from 1860 to approximately 1960.

One of the manual's important features is the flowchart, an outline using a series of questions leading the reader to a preliminary identification. Each process is described in a separate chapter with numerous color illustrations of general and magnified views of select photoreproductions. Each chapter includes sections on how to identify a print, trade names and synonyms, the history and use of the printing process, how a print was manufactured, and degradation and storage considerations. Each of the 54 illustrations, critical for identifying a document's state of condition and extent of damage, have been carefully photographed and checked to ensure correct color representation. Appendices give information on storage and handling, exhibition and current methods of reproduction of architectural prints and drawings.
