Analytical Chemistry 2.0 is a reenvisoning of the print textbook Modern Analytical Chemistry (first published in 1999 by McGraw-Hill) following the return to the author of the copyright. The textbook's title is inspired by a system of software version numbering in which the sequence X.Y.Z identifies a major change in functionality (X), a minor change in functionality (Y), and small changes and/or corrections of errors that do not affect functionality (Z). In this scheme, Modern Analytical Chemistry is equivalent to Analytical Chemistry 1.0, with the transition from a print to a digital format representing a fundamental change in how a user experiences the textbook.

A new edition of an existing textbook is more than a correction of errors and less than a fundamental change in how a user interacts with the textbook; thus, the initial edition of Analytical Chemistry 2.0, which was released in fall 2009, becomes Analytical Chemistry 2.1, which was released in summer 2016. Files for all editions and a consideration of what might make up Analytical Chemistry 3.0 are available using the dropdown menu in the navigation bar or the links here:
