Tip #33: Catalog-only MeSH Terms

By
I was recently digging through some MeSH terms while trying to find a paper about statistics and prevalence in PubMed. I found the following MeSH term: "Statistics" [Publication Type]

...but when I tried to include it in my search string, my results were flagged with a "Quoted phrase not found in phrase index: Statistics" error message:



Ryan Cohen, MLIS, Customer Service Librarian, Contractor for the National Library of Medicine, NIH responded to my confused Tweet with some very helpful information about this type of MeSH term. Thanks, Ryan!

MeSH terms/publication types are used for both cataloging records in the NLM Catalog/LocatorPlus and for indexing the citations of articles in MEDLINE.

There are some MeSH terms/publication types that are only used for cataloging and/or indexing. The statistics MeSH publication type term is only used for cataloging records in the NLM Catalog/LocatorPlus.

See the annotation on the MeSH browser record:

Statistics MeSH Descriptor Data2023: https://meshb.nlm.nih.gov/record/ui?name=Statistics

"INDEXER: Do not use; CATALOGER: Use when 20% or more of the content consists of statistical data. INDEXER: Do not use; CATALOGER: Use when 20% or more of the content consists of statistical data."

Another example:

The Academic Dissertation MeSH publication type term is only used for cataloging records in the NLM Catalog/LocatorPlus:

See the annotation on the MeSH browser record:

Academic Disseration MeSH Descriptor Data 2023: https://meshb.nlm.nih.gov/record/ui?ui=D019478

“INDEXER: Do not use; CATALOGER: Used by collaborating partners and for historical material only”

There are some descriptors that are used for cataloging and other indexing but there is not one unified list of all MeSH that are only used for cataloging in the NLM Catalog/LocatorPlus and only used for citations indexed for MEDLINE. These are some more examples showing Cataloging use the Name Authority. version.
Likewise some descriptors may be broader than usual for the specificity of indexing:
You may also wish to refer to some NLM tutorials which refers to information about the use of MeSH for only cataloging and only indexing, such as:

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]

By

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
