VOLUME CODING FOR BBA-PROTEIN STRUCTURE

BBA is published according to a volume-numbering scheme that embraces all sections of the journal: for I970 the scheme-covering the volumes I96-224-is to be found on the inside cover of this issue. The seven individual sections are distinguished by a colour code. In addition to the colour code each section is given its own sequential volume numbers. This system runs parallel to the overall BBA scheme: for the PROTEIN STRUCTURE section the correspondence is indicated in the Table below. This issue is therefore BIOCHIMICA ET BIOPHYSICA ACTA, Vol. 207/3 or BBA-PROTEIN STRUCTURE PI2/3·
