The Push technique is one of an information technique. It gets over the disadvantage of the Pull technique (the information pull technique) and provides a method with high efficiency and high speed for obtaining information. It will change the transmission and service modes of the information on the Internet and promote the development of the Internet. The application of the Push technique to the literature and information departments such as libraries will change the conventional passive service mode to the active information service mode, and improve the quality of the library information service. In this article, the development and application situations of the Push technique in China and abroad are reviewed, in order to promote the development and application research of this technique in the fields of libraries and information services
The paper analyses the completion of static index technology in traditional full text retrieval system, discusses its merits and fault, then puts forwards a kind of dynamic index technology, elucidates its theory, completes it based on two database development kits.
This paper analyzes the Internet-based information retrieval failure from the selection of retrieval tools/systems and search terms, the formulation and optimization of search request, and sums up the expanding and narrowing searches.
This paper proposes a Web intelligent service algorithm based data mining technology. People can firstly discover the users related-trends and establish a related knowledge base through abstracting and transforming the Web data model. Secondly,make use of the produced knowledge base to anticipate the users actions. So this method can speed up the uses browsing pages. This subject related the discussion is a very important topic in recent intelligent information retrieval field,and has broad theoretical and practicing prospect.
The article reviews the modes of information organization under network environment and also analyses the disadvantages currently. Finally the author puts forwards some suggestions about how to organize and reveal network information resources better.
Personal Alerting system is very important in digital library service. This article analyze Personal Alerting system s infrastructure and discuss some questions in building this system.
Non uniform re sampling and recovery of digital color images stored in BMP format are discussed in the paper. In the re sampling, digital color image are equivalently segmented and then different re sampling frequency, which is automatically determined by using Discrete fast Fourier transform(FFT), is used according to frequency characteristic of each sub region and each color. Experiments and analyses show that recovery quantity and quality is affected by re sampling frequency, energy error, sub-region size, etc.Conclusions drawn from comparing the effects are useful to selection of some parameters. The proposed methods and procedures are not only effective to digital colour image signalst, it is useful to digital videos also.

The paper inguires into countermeasure defend digital libraries copyright from different angles,include governmental support,library legislation ,librarians conciousness,establishing library copyright union and tighten international cooperation among libraries.
Comparison and analysis on the copyright construction of several database for Chinese books that had been or are being of great influence in domestic, namely Boku Company?Chaoxing Company ?Shusheng Company and Founder Company was carried out in this paper. The characteristics and significance of each database were figured out. Four new models for copyright construction was put forward: principle of book tax, principle of copyright permutation, publisher solution at-a-whack, and collective management.
The kernel of Digital Rights Management (DRM) technologies is to lock and limit digital content and its distributing approach in order to prevent digital products from unauthorized copy by security and encryption techniques copyright protection of e-book could be settled by applying DRM technologies in digital library.
Library data storage infrastructure construction is an important part of digital library development. So libraries should select an advanced, reliable and high performance storage solution. Now the RAID is the leading technology in the area of data storage. But with the increase of the amount of data and the amount of visiting, the storage technology that can make full use of storage facilities, with high performance and high extensibility is needed. So NSA and SAN emerged. These two storage technologies that can make full use of storage facilities, with high performance and high extensibility is needed. So NSA and SAN emerged. These two storage technologies are suitable for library’s mass storage.
This paper primarily made an introductory illustration for the basic concepts of information- storage and techniques for disk storing, in particular the technique of RAID in application. After an overall examination of the main information-storage system in use presently and their relevant advantages and disadvantages, the author finally settled on a discussion of the online-information-storage framework, and ambitiously provided a blueprint of its full-range application in the development of digital libraries.
In the information age, researchers information literacy (IL) has become one of the major factors determining a country s research, invention and even the comprehensive national capability and international competitive capability.
