5.A.2. Functional Area A: Level 2 Bibliographic Search and Retrieval
Level 2 inherits all Level 0 and 1 search and retrieval requirements. Conformance with Level 2 allows additional searches for periodical titles and possessing institution as well as additional limiting searches by format/type of material, language of the item and date ranges.
Level 2 searching requires the following bib-1 Attribute Types and Values:

5.A.2.9 Date of Publication Range Search
Use: Searches for items published between two specified dates.
The Date of Publication Use Attribute must be used as a search limiter in conjunction with another operand (i.e., used to limit a search using other Use Attribute values). Z-servers may reject a query that only includes the Date of Publication Use Attribute.
This search must be based on the Z39.50 Implementors Agreement #1 for Linear Range Searching (see http://lcweb.loc.gov/z3950/agency/agree/range.html)
