This enormous undertaking, which, according to one of the prefaces, professes to be a complete list of every bird known at the time of publication, kept growing even as it was being written. The Museum added eagerly to their already vast collections during the decades of publication, acquiring by gift the great collections of A.O. Hume on Asian birds, and those of Sclater and Salvin and Godwin on Neotropical birds, so that the size of the collection nearly tripled between 1874 and 1888. Sharpe originally intended to do all the work himself, but others were called in when this became clearly impossible. The plates are all of birds not previously illustrated. In the decades following its publication this catalogue was universally acclaimed as the most important work on systematic ornithology that has ever been published. (Zimmer, p. 96). And even after one hundred years it remains an essential reference for the serious ornithologist, as it underpins a great deal of modern bird classification. With 387 plates, most hand-coloured lithographs, some chromolithographs, by William Hart, J.G. Keulemans, Joseph and Peter Smit.

: The last 50 years have witnessed a vast expansion of both interest and knowledge in ecology. There has been a widening public awareness of the importance of ecological interactions, with particular focus on issues such as global warming, climate change, extinction of species owing to habitat destruction and sustainable development. In parallel, a wide suite of advances in ecological understanding have been fuelled by progress in a number of other field’s notably genetic engineering and molecular biology. This great expansion in understanding has lead to a problem for the student of the subject, as leading textbooks have grown in size and complexity to accommodate new theories and new data. The present book intended to fulfill the long felt need of the students of graduate and post graduate of all Indian universities. The syllabi of all the universities have been kept in view during the preparation of this text. The language of the book is simple and lucid. Attempt has been made to arrange the subject matter in a systematic and well knit style.
