Arrowsmith Home Page | ## Start ARROWSMITH This search mode will assist you in looking for items or concepts that may be present in common between two distinct sets of articles. Another context for using this search mode is when you want to find information that is present in one field that may be relevant to another field of inquiry. You will be guided through two PubMed searches to retrieve biomedical articles from the Medline database: the first search defines "literature A" and the second defines "literature C." The program then generates a "B-list" of words and phrases found in the titles of both literatures. The B-list can be edited further by selecting only certain semantic categories (e.g. anatomical regions, or disorders, or drugs), by adjusting frequency thresholds (e.g., one can select only B-terms that appear in more than one paper in each literature), by adjusting first publication date thresholds (e.g., one can select B-terms that first appeared in the A or C literature within the last 2 years), or by manual selection of terms. Finally, for each B-term of interest, one can view the titles containing A and B ("AB titles") juxtaposed to the titles containing B and C ("BC titles"). In this manner, one can readily assess whether there appears to be a biologically significant commonality or relationship between the two sets of articles.
