Substantial efforts to establish standards for encoding and accessing
electronic resources have occurred over the past five years. We have d
esigned a Web-based tool, called Spectrum, to enable individuals witho
ut specialized knowledge of library cataloging or markup to create rec
ords for describing and accessing networked electronic resources of va
rious types. System users may create descriptions of electronic resour
ces and view them as formatted USMARC bibliographic records, TEI heade
rs and URCs. Because we anticipate continued volatility in the definit
ion of data element standards, the Spectrum system is designed to allo
w maximum flexibility in the design of the input formats.
