The borrowing rate of books is also called the circulation rate of libraries.
Book circulation rate = the number of books lent in a certain per
The borrowing rate of books is also called the circulation rate of libraries.
Book circulation rate = the number of books lent in a certain period/the total number of books.
Refers to the ratio of the number of books borrowed by readers to the number of readers borrowed in a certain time range, that is, the average number of books borrowed by each reader throughout the year.
The circulation rate of books is the main index to measure the efficiency and social benefits of libraries.
The high circulation rate of books shows that readers' attendance rate is high, the utilization rate of literature is high, and the social benefits of the library are good.
Therefore, improving the circulation rate of books is an important task of library management.
Extended data:
The circulation rate of books is an important statistical data of libraries.
Library statistics
target
The object of library statistics is the quantity of various things in the library.
The contents include: statistics of librarianship, collection of books, readers, library activities, librarians, library funds and construction equipment.
Statistical index
Libraries have various statistical indicators.
① According to the nature, it can be divided into quantitative indicators and quality indicators.
The former indicates the breadth of things, such as the size and quantity of libraries; The latter indicates the depth of things, such as the intact rate of library equipment, the utilization rate of books, and the guarantee rate of books. (See statistical indicators of document circulation).
② According to the calculation method, it can be divided into absolute index, relative index and average index.
Absolute indicators are also called absolute numbers, such as the total number of books, the number of personnel, the number of computers and photocopiers in the library.
Relative index, also called relative number, is the result of comparing two related values, such as the percentage of planned completion.
The average index, also known as the average value, is a typical level, or general level and representative level, in which a certain quantity of each unit in the whole represents different numerical values.
Stage composition
The statistical work of the library includes three stages, namely, statistical investigation, statistical data collation and statistical analysis.
(1) statistical investigation should first make a statistical investigation plan, determine the purpose, object, scope and project of statistical investigation, prepare the statistical investigation form of our library, and determine the investigation method.
According to the survey time, the methods of library statistical survey can be divided into regular survey and one-time survey. The former, such as the number of registered readers visiting the library and the number of books circulating.
According to the scope of investigation, it can be divided into comprehensive investigation and local investigation. The former is a comprehensive survey of library collections, readers, personnel, funds and equipment.
According to the survey organization form, it can be divided into statistical report system survey and special survey, in which the latter can be divided into general survey (such as national or regional literature resources survey), key survey, typical survey and sampling survey.
② The arrangement of statistical data is to systematize the original data obtained from the investigation and make it a working process to reflect the overall characteristics and conditions.
It is the basis and premise of statistical analysis.
The collation of library statistical data can be divided into three categories: periodical statistical data collation, thematic statistical data collation and historical data collation.
To sort out statistical data, an outline must be drawn up in advance, including statistical data grouping, statistical data summary (also called statistical data synthesis) and statistical table design.
③ Statistical analysis is a scientific method to classify and study statistical data by statistical methods, so as to reveal contradictions, sum up experience and improve work. It is an important stage to provide the statistical results of the library.
Statistical analysis requirements: timeliness of analysis, authenticity and comprehensiveness of statistical data, scientificity of analysis methods and comprehensiveness of analysis conclusions.
The steps of statistical analysis are to determine the target and draw up the scheme; Collect information and understand the situation; Analyze and reveal contradictions; Draw conclusions and make suggestions.
The methods of statistical analysis include comparative analysis, grouping analysis, dynamic analysis, structural analysis, factor analysis, equilibrium analysis, correlation analysis and index method.
