This report describes a study to identify the distribution and extent of areas potentially at risk for atrazine (a broad leaf weedkiller) runoff in the Lake Lavon watershed, which is a major water supply for the Dallas area. The report presents the results of the study and makes recommendations for how information can be used in a cost-effective watershed atrazine reduction strategy.

This paper describes a close look at the distribution in constructions of the closed class of complex predicate forming stems in Klallam traditionally called 'auxiliaries.'

An operating assumption for the networked environment is that many different information systems need to interoperate for users to successfully discover and retrieve distributed resources. Meaningful interoperability is often elusive. In the library community, the Z39.50 standard protocol (ISO 23950/ANSI/NISO Z39.50) for information retrieval promised seamless and transparent networked access to library resources. Too often, the reality has not lived up to the promise. This paper discusses two efforts that offer solution paths to Z39.50 interoperability.
