Journals in "my discipline"

Over the weekend, the question came up: what if I want to limit my search to only articles from journals in my discipline?

There isn't an easy way to do this in Medline and the other medical databases. There are, however, some hacks which can be used. If you use these, keep in mind that you may be inadvertently losing articles of value, either by missing a journal in the discipline of interest, or by removing a relevant article because it was in a journal for another discipline.

The strategies available to you depend on the database and interface which you choose to search.

In PubMed, you have two options.

The first is to use PubMed Reminer to analyse your results and pull out journal titles.

Step 1: Put your entire search strategy into one blurb. Copy the search strategy.
Step 2: Go to PubMed Reminer: http://hgserver2.amc.nl/cgi-bin/miner/miner2.cgi
Step 3: Paste your search strategy into PubMed Reminer.
Step 4: If you've already done a search in PubMed Reminer, you can select the Columns to Display on the right-hand side. Uncheck all except Journal.
Step 5: Click the Search button (search with manual adjustment)
Step 6: Above the list(s) of results, click n the link: Save the results as a txt-file.
Step 7: Use the Find feature on your browser to find the text: #T:Journal. (If you selected just the Journal column, this should appear at the top)
Step 8: Copy the list of journals.
Step 9: Paste the list of journals into Word.
Step 10: Starting at the bottom of the list, delete irrelevant journals. Journals with only 1 or 2 in the left-hand column will likely be irrelevant, but watch out for unusual cases such as new journals or quarterlies.
Step 11: Do a Find-and-Replace - In the Find field, type: ^p^#^t and in the Replace field, type: "[Jour] OR " - be sure to include the quotation marks.
Step 12: In the Find field, add another ^# for the two-digit numbers, i.e. ^p^#^#^t and repeat with three ^p^#^#^#^t if you have any three-digit numbers in the left column.
Step 13: Clean up the first and last entry on your list.
Step 14: Copy and paste your new search string into PubMed, and use AND to combine it with your existing search strategy.

The second option is to use the Journals search in PubMed.

Step 1: Make a list of MeSH for your discipline of interest. For example, for palliative care I did: "Terminally Ill"[Mesh] OR "Palliative Care"[Mesh] OR "Terminal Care"[Mesh] OR "Advance Care Planning"[Mesh]
Step 2: Go to the PubMed home page, and click on Journals in NCBI Databases in the right-hand column.
Step 3: Copy and paste your search strategy into the search field.
Step 4: On the left-hand side, click on Currently indexed in Medline
Step 5: On the left-hand side, click on Referenced in the NCBI DBs to deselect it.
Step 6: On the left-hand side, click on English
Step 7: At the top of the page, click on the link that says 20 per page, and set it to show all results at once.
Step 8: Go through the list and check the box next to each journal of interest*
Step 9: When all the journals of interest are selected, at the top right-hand side of the page, click the Add to search builder button.
Step 10: Click the Search PubMed button.
Step 11: Use AND to combine this search with your existing search strategy.

* I'm working on a way to make this step easier. Stay tuned...


Ovid Medline:
Step 1: Make a list of all of the keywords which might appear in the title of a relevant journal. For example, for palliative care, I did: palliat* or support* or end or death or symptom* or hospice or terminal*
Step 2: Enter your list of keywords into the search field, inside parentheses: e.g. (palliat* or support* or end or death or symptom* or hospice or terminal*)
Step 3: After the close parenthesis, add .jw.
Step 4: Click the search button.
Step 5: Combine the results of this search with the rest of your search strategy.

Ovid Embase:
Step 1: Make a list of all of the keywords which might appear in the title of a relevant journal. For example, for palliative care, I did: palliat* or support* or end or death or symptom* or hospice or terminal*
Step 2: Enter your list of keywords into the search field, inside parentheses: e.g. (palliat* or support* or end or death or symptom* or hospice or terminal*)
Step 3: After the close parenthesis, add .jx.
Step 4: Click the search button.
Step 5: Combine the results of this search with the rest of your search strategy.

EBSCO CINAHL:
Step 1: Make a list of all of the keywords which might appear in the title of a relevant journal. For example, for palliative care, I did: palliat* OR support* OR end OR death OR symptom* OR hospice OR terminal*
Step 2: Paste this list into the top search field in the EBSCO interface
Step 3: Change the drop-down menu from Select a Field to SO Publication Name
Step 4: Click the search button.
Step 5: Combine the results of this search with the rest of your search strategy.

Please note: the search history will show text such as the following:
SO palliat* OR support* OR end OR death OR symptom* OR hospice* OR terminal 
You might be tempted to copy and paste this somewhere and use it again at a later date. It will not work. For some reason you must use the drop-down menu to search the SO field, you can't copy and paste the search line from the search history.
