Cheri-- I did not realize that someone had caught the problem with PubMed before I did. I wrote to NLM asking what was going on. Apparently, this is part of the PubMed update 2.0. The reply, which I will foreward if anyone wants to see it...suggested that a search where you can "and" sets and terms together can be done in the BOOLEAN search section, in one long single search query OR if you choose, you can examine the DETAIL of the search query and add to it at that point. Again, using nesting and Boolean logic in one single search statement. (Does anyone remember the very early searching techniques?) BTW, I was told that this field was changed because users wanted to see the number of hits for each term. Using Boolean logic and nesting in a single search statement is difficult for an experienced searcher, but can you imagine teaching it? We had selected PubMed because of the three options available at our location, it was the easiest to use and to teach. And it is a source that can be searched from anywhere in the world. I have written to NLM, and if any of you also feel that we have just stepped back into time, please add your voice to mine. Ask NLM to reinstate the capability to create sets.
