Comment on Something Unnatural about Natural Sciences Publishing Corporation by Laufeyn

Just to add examples…
The “letters” approach is also used by the “Tetrahedron family” of chemistry journals: Bioorganic & Medicinal Chemistry (IF 2.903) and Bioorganic & Medicinal Chemistry Letters (IF 2.338) where the latter is for “preliminary experimental or theoretical research results of outstanding significance and timeliness” and Tetrahedron (IF 2.803) and Tetrahedron Letters (IF 2.397) covering organic chemistry in a similar way as the previous examples (the family also include Tetrahedron Asymetry (IF 2.115) for rapid publication of asymmetric chemisry). It is also applied by the Phytochemical Society of Europe+Phytochemical Society of North America in their Phytochemistry (IF 3.050) and Phytochemistry Letters (IF 1.179) where the latter supposedly is a quicker publication accepting smaller work such as single compound descriptions . All these are currently published through Elsevier.
