Readers: Recently, readers often ask questions about the outline of Chinese core journals (20 1 1 version). We will briefly explain as follows:
1. Abstract of Chinese Core Journals is a research project attended by many periodical workers and experts from related units in Peking University Library and more than a dozen university libraries in Beijing. The research results of the project are published in the form of printed books, and Peking University Publishing House has published five editions: the first edition (1992), the second edition (1996) and the third edition (1996). The sixth edition (version 20 1 1) was published by Peking University Publishing House on February 20 165438. It hasn't been printed yet, and this book won't be available until March and April of 20 12. This achievement has never been published on the Internet, and the various versions of "Overview of Chinese Core Journals" popular on the Internet are not published by this project team.
2. On the issue of "validity period". The outline of Chinese core journals is only the result of a scientific research project. According to the dynamic development and change characteristics of periodicals, they are updated regularly. Its main purpose is to provide reference for periodical purchase, book collection and reading guidance of library and information department. It is not an academic evaluation standard, nor does it have any legal or administrative effect. There is no such thing as "expiration date". How to use it is up to the user. On the issue of determining the so-called "validity period", considering the time difference between the publication and printing of this book and the time difference between the author's submission and the publication of the journal, users are advised not to take a one-size-fits-all approach based on the publication date of the review.
