Cover: R.E.DD.B. (RESP ESP charge DataBase) is a new source of RESP and ESP atomic charge values and force field libraries for molecules as well as molecular fragments. The database contains information for standard residues and their analogs (amino acids, monosaccharides, nucleotides and ligands) covering a vast area of relevant biological applications. A summary on "R.E.DD.B.: A database for RESP and ESP atomic charges, and force field libraries" is published in this issue of NAR. See Nucleic Acids Res. doi:10.1093/nar/gkm887. This cover figure was designed by C. Cézard & F.-Y. Dupradeau.
