"Items in Analytical Abstracts fall into three main categories: Journal articles, technical reports, and books. More than 250 key international journals are scanned regularly by the Analytical Abstracts editorial team. Over 75% of the original material is published in English, with other major languages being French and German, Russian and other eastern European languages, Chinese, and Japanese. Abstracting from non-English-language sources is performed by a panel of chemists with language skills. A small number of other secondary sources are scanned, in order to find items published in more obscure journals or in the non-chemistry literature, for example, environmental, pharmaceutical or geological publications." Inclusive dates: 1980-present.
