Current Collections of Journal Articles

Several entities, including the NIH, National Library of Medicine, and journal publishers have created sites that collate journal articles related to COVID-19, and in some cases, articles about other coronaviruses such as SARS and MERS. Below is a sampling of sites that are easy to use, created by top medical journals, or bring together synthesized evidence in an easy-to-use manner. This is not a comprehensive list. Also note that some publishers only include articles that are published in their journals; thus, lists of articles found on their sites should not be considered comprehensive repositories.

Databases and Search Strategies

PubMed Search Strategies

Katie Lobner from Johns Hopkins University Welch Medical Library has created a thorough search string for COVID-19 searching in Pubmed.

"COVID-19"[tw] OR "COVID 19"[tw] OR "COVID19"[tw] OR "COVID2019"[tw] OR "COVID 2019"[tw] OR "COVID-2019"[tw] OR "novel coronavirus"[tw] OR "new coronavirus"[tw] OR "novel corona virus"[tw] OR "new corona virus"[tw] OR "SARS-CoV-2"[tw] OR "SARSCoV2"[tw] OR "SARS-CoV2"[tw] OR "2019nCoV"[tw] OR "2019-nCoV"[tw] OR "2019 coronavirus"[tw] OR "2019 corona virus"[tw] OR "coronavirus disease 2019"[tw] OR "severe acute respiratory syndrome coronavirus 2"[nm] OR "severe acute respiratory syndrome coronavirus 2"[tw] OR "sars-coronavirus-2"[tw] OR "coronavirus disease 2019"[tw] OR "corona virus disease 2019"[tw]

To narrow these results, consider adding additional topics using AND, or consider using Clinical Queries and choosing an appropriate category for results.

Embase Search Strategies

Embase has a subject heading for coronavirus infections, which can be used a beginning search, with the addition of terms similar to that used in the PubMed search strategy. A simple search for articles in 2019 and 2020 might look like

'coronavirus infection'/exp AND (2019:py OR 2020:py)

A more comprehensive search (while still limiting by date) would be

('coronavirus infection'/exp OR 'coronavirus infection'/exp OR 'coronavirus infection' OR 'coronavirus infections' OR 'covid 19':ti,ab OR covid19:ti,ab OR 'novel coronavirus':ti,ab OR 'sars cov 2':ti,ab OR '2019 ncov':ti,ab OR '2019 coronavirus':ti,ab OR 'corona virus disease-19':ti,ab) AND (2019:py OR 2020:py)


Note that limiting to publication years of 2019 and 2020 will eliminate research on earlier SARS or other coronavirus research to a large extent.

Search Strategies – Special Topics

Clinical Trials

To search for current or planned clinical trials related to COVID-19, you can use the canned search below.

PrePrint Servers

During the COVID-19 outbreak, researchers have been using preprint servers to get research out very quickly. This isn't brand new, but the use of these servers has dramatically increased in biomedical research areas due to the pandemic. That said, you may want to search these servers to find the latest research, with the caveat of knowing the articles presented in these servers are not peer reviewed yet. As medRxiv states on their About page, "Preprints are preliminary reports of work that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information."

Search Strategies in Preprint Servers

Preprint servers can have character limits in their search interfaces. This may require you to cut out some terms in a long string. Otherwise, you can use similar search strategies used in PubMed or Embase without any field tags (i.e. [mesh] or [tw]).

Preprint Servers Custom Search

Seton Hall University has developed a customized Google search that allows users to search multiple preprint servers at the same time.
