Well, I’m not sure my “analysis” was the solution for you, but I did some experiments (just out of curiosity).
I made a new library, switched to online mode, and imported some 50 references from Pubmed using standard connection file came with Endnote. All the journal names were imported as abbreviated, which is different from the recent behavior of my main library. Then, I looked at the Journal term list (in the local mode), and all the abbreviated journal names were placed in the full journal field. For example, “Circ Res” was in the full journal field (ATVB is too long to type, so let me use Circ Res). For each journal name, nothing was in the “Abbreviation 1” or “Abbreviation 2” field.
From this new local library, I imported a reference from Pubmed export text which has TA - Circ Res and JT -Ciurculation Research. I used my custom filter I’ve been using. Then, imported reference appeared as “Circ Res”.
The next thing I did was, I manually typed one term by defining “Circulation Research” in Full journal, and “Circ Res” as Abbriviated 1 field. Imported the same text from Pubmed, then it came out as “Circ Res” again.
Then, I deleted the one that has only “Circ Res” in Full journal name, leaving the manual definition of “Circulation Research”, then the imported reference appeared as “Circulation Research”.
From this experiment, it appears that EN searches “Circ Res”, which comes from the TA line, in the Journal term list from top to bottom order, and then hit “Circ Res” first. This term defines “Circ Res” as full name, so it understands “Circ Res” is full journal name of this reference. But when this term is deleted, it hits “Circulation Research” in the next term, and finds “Circ Res” is matched in the Abbreviation 1 field. Then, use full journal name “Circulation Research” to make this reference. Are you with me??
I’m afraid anybody understood what I’m talking about…Anyway, this explains why Leanne’s library and my library behaves differently. I probably deleted my Journal term list, before I imported from the UQ library’s term list. I guess Leanne “appended” the UQ library’s term list by updating term list. This probably left the “Circ Res” in Leanne’s term list, which makes the most of the import as abbreviated. If this is true, would you look up your term list for Arterioscler Thromb Vasc Biol, Leanne? Is it registered as full name in the term list?
