The annexed catalogue relates to a collection acquired by the India Office Library from the late Professor Aufrecht in the year 1904. The collection consists, as will be seen, partly of Sanskrit MSS., in most cases copied by Professor Aufrecht himself from originals in Europe or India, but including a few copies made, or procured from India, by friends (e.g., Professor Kuhn, Professor Bühler, Professor Kielhorn, and Dr. Stein) or otherwise obtained, and a few originals acquired by gift or purchase; partly of glossaries or word-indices; partly of pratīka-indices, i.e., arrangements of initial words, of verses, mantras, or sütras. In several cases we have the full apparatus of MS., glossary, and pratīka-index to the same work. Many of the MSS. are equipped with collations, and miscellaneous notes are appended to a large proportion of them. We may take account also of a few specialities, such as materials for an edition of the Damayantīkāvya or Nalacampū (No. 53).
