This publication provides a detailed look at the regional public library system for 1981 and presents detailed funding, programming, and staffing information on Texas library systems for use by librarians, trustees, and system staff. Collected from personal contacts and documents and based on certain assumptions or knowledge, the data are intended to draw as accurate a picture as possible of the state library system. The narrative introduction presents a legislative history of Texas systems, a summation of funding for the past 6 years, a review of system membership criteria, and an explanation of accreditation. A statewide overview contains a system map, a table of 1981 membership, the Library Systems Act Advisory Board roster, and the composite Long-Range Planning Matrix of System programs. In the programs section, the information provided for each system includes program abstracts, the collection development incentive formula, 1981 performance objectives, and a list of member libraries. The summary budget analysis section provides the details of the 1981 systems budgets and graphs and charts display this information for the past 5 years. A reader response form is provided for feedback comments, criticisms, and suggestions. (Author/RAA)
