The SCI (Science Citation Index) Journal and SCIE (Science Citation Index Expanded) Journals are very reported Journals. According to Thomson Reuters, the basic difference is saving pattern means SCI journals are specifically saved in form of CD/DVD, but also they are the sub-set of SCIE journals. My question is that "can you please let me understand the difference in more significant way"?
Dear Awani Bhushan,
I attach a response from Thomson Reuters regarding this question for your reading. It will clear your doubt about the difference between SCI and SCIE journals.
Thanks and regards,
Sudev
Hi Awani, here is the answer from Thomson reuters
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.

SCIE (Expanded) is the secondary classification by Thomson Reuter, which in turn is a pool of potentially good journals which do not have impact factor i.e. SCI or SSCI index.
Further, within SCIE, there is no indexing system applicable. Thus, it is simply a tag available to select journals.
Majority of institutes in India and abroad considers SCI and SSCI only, and not SCIE. Lets see, how this classification evolves in the future.

Hi Pushpdant Jain , According to you which journal should be preferred for PhD research publication as per norms of NIT? SCI or SCIE?
" The Science Citation Index (SCI) is a highly selective subset of journals found in the Science Citation Index Expanded (SCIE). Journals in SCI are typically the most consistently high impact titles in many scientific disciplines. "
Dear Awani,
I shall differentiate two by some detail quote which may be given by impact factor and storage formate.
The only difference is the storage media. SCI is only available on CD/DVD format; however, SCIE is available online. Thomson Reuters customer support explanation on SCI and SCIE:. ... The Science Citation Index Expanded is essentially the web version of what used to be a database available only on CDRom/Diskette. Scientific Citation Indexing(SCI) service originally produced by the Institute for Scientific Information(ISI) during 1964. The Science Citation Index Expanded (SCIE) is the larger version SCI which covers more than 8,500 notable and significant journals, across 150 disciplines, from 1900 to the present.
In detail, The journal indexing such as SCI have received more good reputation across the publishing industries to measure performance and citation metrics of both at the journal and author level. The journals indexed under this databased are considered to be the world’s leading journals of science and technology, because of a rigorous selection process. The different indexing categories carried out by the journal evaluation companies create more confusion among researchers to choose the right journal for the publication of their scientific manuscripts.
Brief point of the differences:
SCIE is similar to the SCI except for the two differences:
1. Impact factor: SCI has non zero impact factor but SCIE journals are just ranked for impact factor.
2. Storage formate: Both SCI and SCIE are available online. However, SCI is available on CD/DVD format but SCIE is not.
Hope it helps you out.
