The 14th Edition is the first online-only ASBC Methods of Analysis and is the only edition supported by ASBC. The online-only format allows for continual updating of all methods approved by the technical committees. The online edition includes a number of revised methods added since 2009. Digital Object Identification (DOI) numbers have been added to the 14th Edition, which should be included in citations and will help scientists find the Methods online when they are referenced in scientific journals. Methods that have been revised and replaced by new, improved versions are archived and remain available for reference in the online 14th Edition. Enhancements to the 14th Edition include built-in calculators, video, spreadsheets, audio PowerPoints and colour images.
