ORIGINALS vs. REPRODUCTIONS
It often happens that Houghton will hold an original copy of an item for which another Harvard library owns a microform. Per Harvard policy (see Harvard University Library Bibliographic Standards), all formats generally appear on a single bibliographic record (which describes the original print version), with information about the physical characteristics of the reproduction stored in the appropriate holdings record. [Though see Section XI.6 (Paperbacks and Book Club Editions) for treatment of paperbacks and book club editions.] However, when the card catalog was converted, many of Houghton's original printed editions were added to records for microforms, and many duplicate records for microforms were entered in HOLLIS. In addition, HOLLIS now contains an ever-growing number of records for networked resources, such as EEBO. When upgrading these bibliographic records, delete duplicates where possible and edit the bibliographic record to reflect the print original. Some Houghton holdings records will have "papercopy" in an 866 field---this field should be deleted.
All cataloging for Houghton Library printed materials is added to the HOLLIS online catalog. Catalogers generally create and enhance records in HOLLIS, though at their option they may import records from OCLC after creating/enhancing these there.
