This article introduces a manuscript of the 19th century, hitherto unknown and unpublished, that lies in the Archives of the Bodleian Library, University of Oxford, UK. This manuscript is a collection of biographical notes in Urdu about the Urdu poets of Lucknow. Though the manuscript is not dated or named however the textual evidence shows that it was written by the renowned literary figure of Calcutta, `Abdul Ghafūr Nisākh, somewhere between 1872 and 1887. The manuscript consists of 12 chapters and each chapter unfolds the account of a master poet and his notable pupils. It has been written on large, thin paper and consists of 188 pages in total. It gives the account of 87 poets, and the author has related vivid historical accounts of his period. Most importantly, it describes the social and cultural aspects of life at Lucknow in the 19th century in a very interesting manner. The author has not given any title to his work. The present writer has suggested the title Tazkirah’-e Shu`ra-e Lakẖna’ū for this collection.
