Multi-science prides itself on publishing journals that fill gaps in the scientific literature and are responses to technological developments that call new disciplines into existence. In that way, it achieves uniqueness for its journals, they are not ‘yet another’ journal on any given topic. Of course, all Multi-Sciences primary journals are fully refereed; the fact that distinguished editors and editorial boards lend their names and their time to the journal is one way of understanding the esteem in which they are held in certain quarters. As well as journals, Multi-Science publishes books in the same subject areas as its journals. Multi-Science publishers mainly in the following areas: engineering, with an emphasis on acoustics and construction/built environment; energy and environmental studies, including renewable energy and energy policy; aerospace/aeronautics; and sports science. Further areas are medical engineering; fluid dynamics; theory of innovation.
