Note: Prior to Volume 123, each volume included primarily the literature of the year shown in the table above, together with any items, which for various reasons, were omitted from earlier volumes. For Volumes 123 onward, coverage expanded to include all items available during the indexing period, from July to June of the following year, thereby ensuring that relevant items are indexed as soon as possible.
