A survey of 136 science faculty, graduate, and undergraduate students, and focus group interviews, provided perceptions and input to be used to rethink the science library's organizational structure and services. Users felt the following to be important library services: consulting the Melvyl databases; borrowing books; interlibrary loan services; using photocopy machines; consulting library materials; receiving help at the Reference Desk, especially in the evenings and on weekends; checking out reserve materials; using the library as a place to study; and consulting UNIX. Important future services include finding articles on specific research topics; instruction on the Melvyl databases and electronic resources of the Cowell Room; electronic mail reference questions and notifications of overdue books, recalls, and holds; electronic reserves; placing holds from the online catalog; and ordering all needed materials through any Melvyl databases. Six focus groups interviews were conducted, and responses are provided for each focus group on 12 unstructured questions. Data is presented in 44 figures. Ten appendices include statistical results and a summary of suggestions from each survey group, a list of focus group questions, and summaries of each focus group interview. (MAS)
