(index of science and technology; Journal of Technology (ISTP) was founded in 1978 and edited and published by institute for scientific information, USA. In international academic exchanges, academic conference documents are very important original documents. New theories, new plans, new signs and new ideas are often distributed at academic conferences and published in the form of meeting minutes. Because some conference papers may not be published in journals, it is very important to retrieve conference papers, and conference proceedings are the main publications for publishing conference documents.

Classification: institute for scientific information (ISI) integrates ISTP (index of scientific papers) and ISSHP (index of social humanities papers) into ISI papers based on the Web of Science retrieval platform. The integrated ISTP is divided into two kinds of retrieval: CPCI- Song Seung Heon and CPCI-S, so it is also collectively called ISTP, and some people call it CPCI.

ISTP retrieval is actually a global database, similar to HowNet in China. However, not all articles in ISTP are entered, and all entered articles represent authority and high quality. Therefore, ISTP is called the global core and is recognized by every country.
