About ICDS

The ICDS (Secondary Composite Index Broadcasting) is an indicator that shows the visibility of the journal in different scientific databases of international scope, or failing in repertoires evaluation of periodicals. A high ICDS means that the magazine is present on different sources of information of international relevance. For the calculation of ICDS the following criteria are established.

  • If the journal appears in Web of Science Core Collections (AHCI, SCIE, SSCI o ESCI) or Scopus it is assigned a score of 3,5.
  • If the journal appears in WoS classic indexes (AHCI, SCIE or SSCI) and Scopus it is assigned a score of +1.
  • If the journal appears in an abstract and indexing database (specialized or multidisciplinary) it is a assigned score of +3.
  • If it included in two or more specialized or multidisciplinary databases is assigned 5 points (3+2).
  • If not appear in any database indexing but it's appears in the Latindex catalog (not to be confused with the Latindex directory) or a repertoire of assessment (CARHUS Plus, CIRC, SJR y sello de calidad FECYT) it is a assigned score 2,5.
  • If it appears only on the DIALNET Spanish database 0,4 points are assigned.
  • Finally, the calculation is completed with the rate of survival of the journal, which is calculated based on the logarithm of the total years of life the title from the beginning of its publication, considering a maximum of 30 years in the calculation.

MIAR shows in the register of each journal how he obtained his ICDS and also details what group databases, or repertories appears.

Changes in the ICDS 2016 calculation

Now the value is rounded to the first decimal. Regarding the score given upon the presence of titles in bibliographical databases, there are two changes: 3+2 points are given when a title is covered by two or more abstracting and indexing databases, without distinction between specialized or multidisciplinary; an additional +1 point is granted to titles that are indexed simultaneously in Scopus and in WoS classic indexes (AHCI, SCIE o SSCI).
