About Us

In addition to continually working to enhance the visibility of articles on our website, SAGE works with a range of external indexing partners.

We work with a large number of external indexing and database services to maximise the visibility of authors' articles.  Journal's homepages contain partial lists of the external databases and indexes they appear in.  We only list external indexes and databases on journal homepages that we have formal agreements with.  The list below gives all database we know to contain one or more journals' content:

  • Chemical Abstracts Service

  • Chinese Electronic Periodical Service

  • Directory of Open Access Journals

  • EBSCO: EBSCO Academic Search International (formerly Academic Search Complete), EBSCO CINAHL Complete, EBSCO Environment Complete, EBSCO Health Policy Reference Center

  • Excerpta Medica: Embase, Embiology, Emcare

  • Gale: Gale Academic OneFile, Gale Health Reference Centre, Gale InfoTrac Custom journals, Gale Resource on the Environment, Energy, and Natural Resources, IT Academic OneFile - Agriculture Collection Periodical

  • Google Scholar

  • Index Copernicus

  • Intute

  • OAIster

  • Open J-Gate

  • ProQuest: British Nursing Index, Illustrata-Natural Science, Illustrata-Technology, ProQuest Agriculture, ProQuest Aquatic Science, ProQuest Atmospheric Science, ProQuest Biological Sciences, ProQuest Computer Science, ProQuest Engineering, ProQuest Environmental Sciences, ProQuest Health & Medical Complete, ProQuest Materials Science, ProQuest Natural Sciences, ProQuest Public Health, ProQuest SciTech, ProQuest Technology

  • Pubmed: Pubmed Central

Journal Directories

SAGE Publishing journals appear in many journal directories including:

  • Academic Journals Database

  • ChemSpider



  • JournalSeek

  • JournalTOCs


  • Pubshub

  • RefSeek

  • SafetyLit

  • SciNet

  • Scirus

  • Ulrich's Periodicals

Because Scopus occasionally adds or removes journals without notification, SAGE regularly verifies that database coverage information is correct.  Coverage information was most recently verified on September 2016. 

All published articles are archived by CLOCKSS and LOCKSS, and most content is also archived by Pubmed Central to ensure perpetual availability to readers.

CLOCKSS is a venture between the world's leading scholarly publishers and research libraries.  It operates a sustainable, geographically distributed archive to ensure the long-term survival of web-based scholarly publications for the long-term benefit of researchers around the world. To learn more visit the CLOCKSS participants list and read the CLOCKSS press release.  LOCKSS is based at Stanford University Libraries and provides ACM award winning digital preservation of scholarly content.  Like CLOCKSS it is an internationally-distributed archive where libraries around the globe retain all intended content.  

Between 50% to 75% of published articles are currently archived in Pubmed Central, operated by the NIH, and this figure will continue to increase as additional journals are added to Pubmed. 

Is there a risk of my paper disappearing?

No. All open access articles are permanently archived by CLOCKSS. SAGE has operated continuously and on a commercially-sustainable basis since 2005, but in the unlikely event that it should cease operation all articles will continue to be permanently available from CLOCKSS, as well as other archives and indexes such as Pubmed.

Can I archive my paper?

We encourage authors to self-archive if they wish.  More information is available here.

How does a journal obtain an impact factor?

The only provider of genuine impact factors is Thomson-ISI.  Journals must be carefully prepared for an impact factor evaluation.  They must meet various criteria before an application can be made.  The journal must have published a minimum of fifteen papers in a nine month period or twenty in a twelve month period.  These papers must achieve reasonable citation rates.  The journal and papers published in it must demonstrate that the journal meets various editorial criteria.  

Prior to making an application we also consider the quantity of papers expected to be submitted and published following the commencement of the evaluation period.  Where available we give consideration to the journal’s performance in similar citation metrics.  For this purpose SCImago is our primary information source.  

Evaluations typically take a minimum of nine months.  If an evaluation is unsuccessful the journal cannot be re-evaluated for a period of several years and in extreme cases—after several reevaluations—may be permanently ineligible for evaluation.  Even if Thomson-ISI’s editors determine that a journal meets all the criteria they may nevertheless decide not to provide it with an impact factor.  For these reasons it is important to prepare journals as thoroughly as possible for evaluation, and to not apply for evaluation before they have met or exceeded all criteria.  

What journals have impact factors?

Where a journal has an impact factor it will be indicated with a green tag on the journals homepage and the impact factor will be given on each individual journal’s homepage.

Why does a journal not have an impact factor?  When will it get one?

We recognize the continued importance of impact factors to authors and readers, so where a journal does not already have an impact factor it is under preparation for one.  Journals achieve the various criteria required prior to an application at different rates, so a journal’s age does not necessarily indicate that it is eligible for an impact factor.  In particular, many of our journals meet all the criteria except for the required quantities of published papers.  This is a reflection of our high rejection rates and can only be addressed by attracting more high-quality manuscripts, which is a key priority for SAGE.  Despite recognizing the importance of impact factors, we will not undertake conduct that would prejudice our editorial standards in favor of obtaining impact factors, such as lowering editorial standards or entering into citation manipulation cartels.  

Because the outcome of Thomson-ISI’s evaluations is difficult to predict we cannot identify journals currently under evaluation, nor can we comment on when an outcome will be obtained nor what we expect the outcome will be.  

An approximation of a journal’s impact factor can be obtained from SCImago, which calculates impact factor-like metrics based on data provided by Scopus.  Where these are available we make them available on the applicable journal’s Analytics tab, near the top right of the journal’s webpages.  More information on the SCImago metrics is available from applicable journals’ Analytics tabs.  We have observed significant variations between official impact factors and those provided by SCImago: for example the official impact factor of Evolutionary Bioinformatics was 1.452 in 2014 and SCImago’s equivalent estimate in 2014 was 0.96.  We emphasize that SCImago’s metrics should not be considered as substitutes for genuine impact factors.  

What happens after a journal receives an impact factor?

We will announce the journal’s impact factor on its website and through other channels.  After an impact factor is received it will be updated annually and we will update the journal’s website accordingly.  The year—shown in brackets beside the impact factor—indicates the currency of the impact factor.  

Typically impact factors calculated in the years immediately following the first year show a decline, followed thereafter by a recovery.  This is normal and is thought to be a consequence of the increased rates of manuscript submissions seen by journals with impact factors.  

An expanding quantity of our journals have h-indexes calculated by SCImago.  To view SCImago data, which includes a selection of metrics, visit the SCImago website.

Article metrics are available for all articles within approximately 72 hours following publication.  Article metrics are based on data collected on the journal's website and where applicable also from Pubmed Central.  Metrics include HTML and PDF views, views per month, and views per geographical region.  To view this data go to the article's abstract and select the Article Metrics tab.

What Your Colleagues Say About SAGE
My laboratory has published several papers in Cell Communication Insights. In each case, reviewer comments were returned promptly; the suggested revisions were both fair and quite helpful, reflecting positively on the quality of the review.  Once accepted, the editorial office provided clear and frequent updates on the progress of our manuscripts through each step of the publication process.  When necessary, I had prompt email responses to my questions and the figure quality was exceptional.   Keep ...
