目的：为了评估两个公开的烟草行业的文件集合进行搜索的可比性：保存和保持由一个中立的一方在明尼苏达州的存储和电子副本，通过烟草行业维护websites.Methods：我们进行了一组搜索在明尼苏达州，然后进行了相同的搜索使用行业网站。我们匹配的文件贝茨数，淘汰重复，和编码的文件，是唯一的，无论是收集主要的，次要的，或trivary.Results：在数百个文件中产生的几个搜索，我们发现只有四个独特的主要文件在明尼苏达州存管。相比之下，我们发现62个独特的主要文件使用的网站。结论：这些结果表明，研究人员可以依靠行业网站，同时等待烟草控制社区管理的搜索，索引和文件存储带来的访问改善。搜索烟草行业网站至少和在明尼苏达州搜索一样好，在某些情况下可能更好。然而，四个较小的子集合只能在明尼苏达州手工搜索。
Objective: To assess the comparability of searches conducted on two publicly available tobacco industry document collections: hard copies housed and maintained by a neutral party in the Minnesota Depository and electronic copies available through tobacco industry maintained websites.Methods: We conducted a set of searches in Minnesota and then conducted the same searches using the industry websites. We matched documents by Bates number, weeded out duplicates, and coded documents that were unique to either collection as major, minor, or trivial.Results: Among hundreds of documents produced by several searches, we found only four unique major documents in the Minnesota Depository. By contrast, we found 62 unique major documents using the websites. Conclusion: These results suggest that researchers can rely on industry websites while waiting for improved access resulting from searching, indexing, and document storage administered by the tobacco control community. Searching the tobacco industry websites is at least as good as searching in Minnesota and may in some instances actually be better. Four smaller subcollections, however, can only be searched by hand in Minnesota.
