The fundamental handbook for analytical spectroscopy. Release of the second edition of ‘Chemometrics in spectroscopy’ by Howard Mark and Jerry Workman, Jr. and its impact on the spectroscopic community

In the last year, an event of a marked significance for the spectroscopic community had taken place. The second edition of Chemometrics in spectroscopy, by Howard Mark and Jerry Workman, Jr. has been published. In relation to its first edition, this plausibly the most renowned chemometric-based tutorial book has been significantly expanded with new content covering the substantial progress that has occurred in the field over the last decade. The comprehensive tutorial has been augmented by both the revised and newly added sections exploring the most recent hot topics in analytical spectroscopy. These include, but are not limited to, aspects directly and indirectly corresponding to calibration and spectral transfer, principal components, regression models, classical least squares, units of measure in spectroscopy, clinical data analysis, and other highly relevant topics. In the present short review, we sketch the features and improvements introduced in the re-released epic handbook for chemometricians and spectroscopists, providing the reader with a summary of essential information helpful in deciding whether this book should land in his library shelf
