Acknowledgments The discussion of the theoretical basis of semi-empirical methods would not have been possible without the help and advice of several friends and colleagues, including Drs. Yngve Ohm, James Stewart, Michael Zemer, Henry Rzepa, and Marshall Cory, Jr. I am also indebted to the authors of many previous reviews of semi-empirical methods and to Anne-Marie Sapse for her patience. 

Second, even if one can access the content of a journal article page, it is generally not in a format that makes it easy for a computer to process the information contained in it. In particular, the PDF format is most commonly used, in which chemical structures and spectra become images, and data tables become plain text. Maybe a journal article refers to a melting point of a compound that would answer the query of a particular scientist, but how would a computer locate this information in the text The cause of creating machine-readable versions of journal articles and other documents in the chemical sciences has been championed by Peter Murray-Rust and Henry Rzepa (2004), who have coined the term datument to refer to a document that is fully marked up in machine-readable form, so that meta-information about data is fully preserved.
