Comparing 2 databases (ex: ovid and pubmed)
hi, I have question regarding comparing 2 databases.
for example, I downloaded citations from pubmed (in one foler) and also ovid (another folder).
is there any way to compare both side by side, so I can manage which one I already have ... than delete the one I dont need from one folder.
the duplicate feature allow me to choose and merge the citation, but the problem is, still appear in both folder.

thanks

and
the second one is I download list articles from Ovid into Ovid directory.
of course I dont want to do the same process from previous database in pubmed directory.
all I want is to automatically match, wich article that I already have in pubmed dir, and delete from ovid dir.
the duplicate feature only do merge if it found two (or more) article in library.
this matching features is very useful if we do literature review and comparing from many databases.
will save lots of time
Are you evaluating the contents of each database (PubMed and Ovid) to assess the coverage by keyword? Are you looking at PubMed direct versus PubMed via Ovid or are you using Ovid for other databases in addition to PubMed? I've done research on the differences in literature database coverage of articles on selected topics. I used Zotero as the first step. However, there are several other tasks that must be done outside of Zotero to make the comparisons.
than you for the tips. I will try it. because in last time I tried, in duplicate folder, if I click the articles , all will be highlighted.
@DWL-SDCA
of course I aware that merge resulted in same version in both collection.
and yes, I have to do outside zotero many task.
also both databases will result different result.
in this context, is about whether zotero have ability such as dbms which can compare side by side both folder (that I created for different databases search result) and deleted or short which have duplicate and than I will remove the one that I dont need.
this will make easier or less work, rather than I have to do the same picking out articles that I already done in first folder.
thank you
I search with keywords "paperless".
2 databases use, pubmed and ovid medline.
search with pubmed result 5, and moved to group pubmed
search with ovid result 4, and moved to group ovid
now, I need to remove duplicate in these two groups. just go to references -- find duplicate -- and I choose "keep"
result : group pubmed 4 citation left, and group ovid 2 citation. TOTAL citation 6.
NOW, in the case of Zotero
i do the same thing, and the result each will move to pubmed and ovid collection (same thing with group in endnote)
and, now I will remove duplicate.
We will see basically 2 option, either merge (choose which one as master) or right click delete.
the RESULT ?
if we MERGE , there will be only 6 citation in My Library
BUT
in Pubmed collection still have 5 and in Ovid collection still have 4 collection
if we DELETE , you know .. will remove either from collection or my library.
THE BIG question , how to get the same result like in endnote ? rather than in zotero (my example)
Besides what adamsmith said above (about right-clicking a single reference in the duplicate "window" and selecting delete), I don't think this is possible in Zotero to be done automatically.
But I'm not clear on where this is useful. I can imagine two situations:
(1) I want to compare two databases to see what articles are present in one database, but not the other.
Solution:
- Collection -- is -- pubmed
- Collection -- is not -- ovid
This will return all items in pubmed, but not in ovid. You may want to save this search and/or tweak some settings on the advanced search panel.(2) I am doing a literature review (seems like what you are going for) and I don't want to read the same articles I already read in the other database.
Solution:
(You can of course just do the same thing as in solution to problem (1), but here's an alternative)
- Place both collections in another collection. E.g. "litReview"
- Merge duplicates just the way Zotero does now.
- Turn on "recursiveCollections" hidden preference
- Look at items in the "litReview" collection. This will display a single copy of each item from both ovid and pubmed collections.
Is there another use case that cannot be solved with either of these methods?Edit: added link for advance search feature
