Indexing & Archiving

Indexing & Archiving Policy – ESTEM Inc.

1. Purpose of Indexing & Archiving

Indexing enhances the visibility, accessibility, and scholarly impact of published articles by enabling researchers, institutions, and discovery platforms to locate and evaluate research outputs efficiently.
Archiving ensures the long-term preservation and permanent accessibility of scholarly content, independent of future technological or platform changes.

2. Indexing Objectives

The indexing policy of ESTEM Inc. is designed to:

3. Active and Ongoing Indexing Partnerships

Each journal published by ESTEM Inc. is individually evaluated for inclusion in indexing and abstracting services.
Indexing coverage expands progressively as journals demonstrate editorial maturity, regular publication, and citation performance. Inclusion is subject to independent review by indexing agencies.
