Tip #29: Filtering by Date Added in Scopus

By

This week's tip comes to us from Paije Wilson, MLIS Health Sciences Librarian at the Ebling Library. She credits the Systematic Reviews, Scoping Reviews, and other Knowledge Syntheses guide from McGill Library as the original source for the tip.

You can filter results in Scopus by date added to the database. I've found this handy when researchers want everything added to a database after or before a specific date, regardless of when the items were published.

ORIG-LOAD-DATE > [insert Unix time without brackets or year month day]

ORIG-LOAD-DATE < [insert Unix time without brackets or year month day]

For example, ORIG-LOAD-DATE > 1616907600 or ORIG-LOAD-DATE > 20210328 will retrieve items added to Scopus after March 28, 2021 (regardless of publication date). 


You can also AND a before and after filter together to get a date range. I've only seen this tip on a couple of pages, including this blog page (https://christinaslisrant.scientopia.org/2014/04/29/searching-scopus-by-date-added-to-the-database/) and McGill's libguide (https://libraryguides.mcgill.ca/knowledge-syntheses/updating).

That McGill guide has filters for load dates for other databases too!

Tip #1: Bulk export from Google Scholar

This post was updated on October 10, 2022 with new instructions for #3 under "For EndNote users..." For years, I kept hearing from colleagues that I should be searching Google Scholar as part of my systematic review projects. I didn't, for 3 reasons: I didn't know GS' search syntax GS notoriously does not allow bulk export to reference managers I didn't have a sense of how many results I should export.   Last fall, I finally said enough was enough and it was time to learn how to wrangle this beast. It turns out that there is now a third-party tool that facilitates bulk export from Google Scholar, Harzing's Publish or Perish . Here's how you get started: Download PoP for free Paste your query into the Keywords field Set your maximum number of results. I follow the guidelines on p. 135 of Wichor Bramer's dissertation , which is a great handbook for expert searching. Bramer suggests the first 200 results, or 100 if you are getting low numbers of res

Tip #23: PubMed's [tiab] vs. [tw]

Search field tags are a quick way to specify the exact fields you would like to search when using keywords. For example, I can tell PubMed to search for my term only in the title field or only in the MeSH Terms field. You can view a list of available search fields from the drop down menu in PubMed's Advanced Search Builder. Specifying field tags for keywords is also a good practice in PubMed because keywords searched without field tags will be translated through Automatic Term Mapping which may reduce the precision of your results. Here are a few sample searches in my search history, including #4 which wasn't limited to a field (notice how it was translated in the expanded search details): The fields that are included in the [title/abstract] fields are pretty self-explanatory (words and numbers included in a citation's title, collection title, abstract, other abstract and author keywords), but what is actually included in the [Text Word] (can also be searched as [tw]) fi

Tip #4: Ovid MEDLINE Adjacency and Field Tags

By

This tip was submitted by Kathryn Vanderboll (University of Michigan):  In Ovid MEDLINE, using adjacency with .kw. does not work the way you (probably) want - use .kf. instead! While searching (surg* adj (educat* or instruct* or learn* or teach* or train*)).kw., our team couldn't figure out why our sentinel article tagged with with the author supplied keyword "surgical teaching" wasn't showing up. Through trial and error, we learned that .kw. adjacency only works between lines . That is, how close keywords are to each other on different lines. For example, (surg* adj teach*).kw. picks up articles with keyword headings like:  But does NOT pick up articles that might have keyword headings like:   To use adjacency searching within a single keyword heading, you'll need to use .kf. The Ovid help documentation notes : "The Keyword Heading (KW) field contains the Keyword Headings assigned by authors. Keyword Headings are the author keywords. To retrieve every Key
