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 databases 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

SAGE Publishing journals appear in many journal directories including:
Academic Journals Database
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.
We encourage authors to self-archive if they wish. More information is available here.
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. We are working closely with Clarivate Analytics (formerly Thomson Reuters) to ensure that our published articles will be available in their databases when appropriate.
Article Usage Metrics
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.
