Development of an Internal Web Site for a Law Firm

Abstract

The Information Services Department at the Washington, DC law firm, Dickstein Shapiro Morin & Oshinsky, decided in 1995 to provide firmwide access to the Internet. Two separate World Wide Web home pages would be created to meet the divergent needs of the Marketing Department and the information resource requirements of the attorneys, who would be using the Internet for research. In the course of developing Internet pages for the firm, the Library began working in conjunction with attorneys in various practice sections to locate and create Internet resources. The cooperation between attorneys and the Libraiy has led to Internet pages of hypertext linked resources for each specific practice section within the firm. Furthermore, some of the pages of resources have evolved into home pages for the various sections.     

A Review of “What They Don’t Teach You in Library School”

SUMMARY

Distance learning students may not think of the “campus” library as the first place to fulfill their information needs and may not even be aware of the services available to them. One way to reach these students is to adopt and adapt marketing techniques from the business world. This article examines the findings of a survey conducted at Emporia State University concerning the awareness of distance learning services. It will also examine marketing techniques and illustrate how they can be applied to increase awareness of reference support services for distance learners.     

The Buck Stops Where?

SUMMARY

University students-whether adult, distance learner, or traditional age-need access to university services and quick accurate answers to their questions beyond traditional “business” hours. Students' busy schedules and changing life patterns dictate that university services meet their needs. At DePaul University in Chicago, student focus groups repeatedly pointed to the need for one central place to get an answer or solve a problem. DePaul Central was created as an information and referral service to satisfy that student need, at the same capitalizing on the value of the librarian skill set.     

A Historical Overview of Internet Reference Services for Distance Learners

SUMMARY

The advent of library services and collections on the Internet revolutionized reference services to students enrolled in distance learning programs. Prior to the Internet, reference librarians who supported distance learning programs had few methods, and many of them costly, to provide the equivalent library services advocated by the ACRL Guidelines. Through the Internet, these librarians were able to approximate the services and resources that had always been available to students who came into the library. This article describes the development of reference services on the Internet in a variety of libraries that support distance learners.
