Growth of Literature over Consecutive Decades

It is evident from Table 1.2 (supplemented by Fig. 1.2) that 1870’s ranks first as there is an enormous
increase of 400% of literature over its previous decade due to the fact that literature in the field was
just starting to boom. The 2nd and 3rd ranks are occupied by 1890’s (100%) and 1950’s (85.50%) of
literature over their previous decade.
