What is the basic difference between between the SCI (Science Citation Index) Journal and SCIE (Science Citation Index Expanded)? Does it matters in case of quality of journal?
Thanks

Yes there is a big difference so SCI journals are also expanded but the converse may be not true. In mathematics the list of SCI journals is so limited.
Excellent comment dear Dr. Monyer Abd Al-Fatlawi I do agree with you.

The Science Citation Index (SCI) is a sub-set of the Science Citation Index Expanded (SCIE), containing journals that rank competitively among the most highly-cited core journals in their category or categories. The Science Citation Index Expanded is essentially the web version of what used to be a database available only on CDRom/Diskette.
When selecting the journals for the Science Citation Index we choose the top journals from each subject category and supplement this with top regional journals from each category to give broad geographic and multidisciplinary coverage. The evaluation of and acceptance of a journal for the Science Citation Index Expanded or the Science Citation Index is essentially the same with one major difference.
This difference is in the application of citation analysis to the journal. While every science journal in our database is covered in the Science Citation Index Expanded and only those journals of relatively significantly higher citation impact are selected for the Science Citation Index. In other words, Science Citation Index covers only the most highly cited, highest impact journals in each category. This is because of the constraints of the CDROM and print media there is no difference in the selection process for Science Citation Index and Science Citation Index Expanded journals.
Dear Thomson,
Please note the similarity/difference between SCI and SCIE journals (in brief):
- All SCI journals are found in SCIE database, but not all SCIE journals are available in SCI database
- Evaluation and acceptance process of a journal for the SCI or SCIE are same
- Difference - The only major difference in storage media. SCI is available on CD/DVD format, where as SCIE is available online
- SCI is a subset of SCIE and probably includes the high impact factor journals. Best wishes
