In the last issue, we introduced the Elsevier journal database, and in this issue, we will continue to introduce the EI database, mainly leading you to understand the use of the EI database and the charging and procurement, you can refer to it, and you will not be clueless when purchasing in the future.

Okay, without further ado, let's go straight to the dry goods.

It is mainly divided into three aspects.

1.What is EI Database?

2.How much does EI database cost?

3.How to use the EI database to procure?

1. What is EI database?

The current full name of the EI (Engineering Index) database is "Engineering Village Compendex", also known as "EV Compendex" and "EV CPX".

EI database is currently the world's most comprehensive secondary literature database in the field of engineering published by Elsevier, covering a series of high-quality literature resources in the field of engineering and applied science, involving mechanical engineering, civil engineering, environmental engineering, electrical engineering, structural engineering, materials science, solid state physics, superconductors, biological engineering, energy, chemical and process engineering, lighting and optical technology, air and water pollution, solid waste treatment, road traffic, transportation safety, control engineering, engineering management, Agricultural engineering and food technology, computer and data processing, electronics and communications, petroleum, aerospace, automotive engineering, and sub-sciences in these fields and other major engineering fields.

In terms of resource content and quantity, the EI database has more than 23 million records; It includes more than 3,600 journals, more than 10,000 conference proceedings and industry magazines every year; Covering more than 190 fields of engineering and applied science; **Content included in 1969 to present; More than 1.3 million abstract citations are added each year, and the database is updated weekly.

In terms of resource retrieval system and function, EI database provides a variety of search methods, including quick search, expert search, thesaurus search, author and institution search, to meet different search needs. It can be used to limit the search of document type, document language, document time limit, etc.; Provide personal account and password, save personal search history and set up email notifications; Access is controlled through IP addresses, and private line services are provided without concurrent user restrictions.

In addition to being used as a retrieval tool, the number of ** included in EI is also used as an objective indicator to evaluate the academic achievements of scientific research institutions or researchers.

The EI (compendex) database is an abstract database, not a full-text database, which generally only includes the bibliography, abstract, keywords, and references of the literature, plus subject headings, classification numbers, etc.

engineering information inc., which is now part of Elsevier. When searching with EL, there is a full text on the literature search history page'options can be found in elsevier.

The ** included in EI is divided into two grades, one is the CD-ROM version of the Engineering Index (EI Compendex), which is provided by the American Engineering Information Corporation, and the data is selected from more than 2,600 international engineering journals, scientific and technological reports and conference proceedings; Another type of EI Compendex Web is the online version of the Engineering Index, which includes the original CD-ROM version (EI Compendex) and later expanded sections (EI PageOne), which focuses on abstract indexed information in the fields of science and engineering. The difference between the two is whether there is a subject heading and classification number indexing.

2. How much does the EI database charge for use?

How much does the EI database cost, let's look at the new procurement**.

The purchase price of a university's EI database is about 200,000 yuan.

The approximate support time of this ** is one year, which is still relatively expensive.

It can be seen that most of the current announced purchases are also some relatively well-known universities, and for some ordinary universities or some scientific research institutions or R&D departments that use less databases, this price is difficult to bear.

So what should be done about this part of the demand?

Today I would like to introduce to you a new way of procurement, Zhangqiao [Foreign Language Database (Institutional Edition)]:
