The OpenRS Format Filter is located on the lefth and side of the screen in OpenRS, along with other filters for Location, Publisher, etc. The filter is designed to limit and refine searching on OpenRS.
Format in OpenRS is derived from the MARC Leader byte 06 (Type of record) and in some cases byte 07 (Bibliographic level). The formula for how these values map to the Format code in OpenRS is as follows:
|
