Tosh Yasutake of the USGS Western Fisheries Research Center has digitized the histology plates from his "Histopathology of Selected Parasitic Salmonid Diseases: A Color Atlas" and made them available in several formats on the USGS web site.
The Blue Book includes three sections: Diagnostic Methods, Procedures for Aquatic Animal Health Inspections, and Quality Assurance. All three sections of the NEW 2014 Blue Book are, FOR THE FIRST TIME EVER, available ABSOLUTELY FREE by clicking on the Blue Book tab at the left of this page. The Blue Book is no longer for sale on DVD through the AFS.
