Citation analyses takes place on at least two levels. We look for citations to the journal itself, as expressed by Impact Factor (IF) and/or total citations received. We also examine the citation record of the contributing authors, a useful study in evaluating new journals where a citation history at the journal level does not yet exist.
Likewise, established journals that are not covered are often re-evaluated. These journals can experience new growth in citation impact resulting from changes such as translation into English, change in editorial focus, change in Publisher, medium, etc.
Because Thomson Reuters captures all cited references from each of the 9,300 journals covered, citation information is available on journals not covered as well as those that are covered. Self-citation rates are also taken into consideration. The self-cited rate relates a journal's self citations to the number of time it is cited by all journals, including itself.
For example, journal X was cited 15,000 times by all journals, including the 2,000 times it cited itself. Its self-cited rate is 2/15 or 13.3%

Basic Journal Standards
Timeliness of Publication is a basic criterion in the evaluation process. It is of primary importance. A journal must be publishing according to its stated frequency to be considered for initial inclusion in the Science database. The ability to publish on time implies a healthy backlog of manuscripts essential for ongoing viability.
It is not acceptable for a journal to appear chronically late, weeks or months after its cover date. To measure timeliness we need to see three consecutive current issues, one after another, as soon as they are published. Timeliness is also essential for electronic journals. If the e-journal is publishing distinct issues at a stated frequency, these issues should appear online in a timely manner.
However, when an e-journal publishes articles one at a time rather than collecting articles for release as an "issue" we take a slightly different approach to measuring timeliness. In these cases the editors look for a steady flow of articles over several months time.
