This fifth edition of "The Guide to Microform Holdings in the Bodleian Library" replaces the 1995 edition, and contains almost 70 more entries than its predecessor. The guide does not attempt to record every microform item in the Library. It does not list microform copies of individual monographs or periodical titles (except newspapers), nor does it include microform material acquired to fill gaps in the holdings of sets which are predominantly available in printed form. The guide's aim is to serve as a convenient reference tool which includes all the Bodleian's most substantial collections in microform, together with fuller coverage of those bibliographies, official publications and newspapers which are held in micro-format.
