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.
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.
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.
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.
评估对两个公开的烟草行业文件集进行检索的可比性，这两个文件集分别是：由明尼苏达州存放处的中立方保存和维护的硬拷贝，以及通过烟草行业维护的网站获取的电子拷贝。
我们在明尼苏达州进行了一系列检索，然后使用行业网站进行相同的检索。我们根据贝茨编号匹配文件，剔除重复项，并将两个文件集中各自独有的文件编码为主要、次要或琐碎文件。
在多次检索产生的数百份文件中，我们在明尼苏达州存放处仅发现了4份独有的主要文件。相比之下，我们使用网站发现了62份独有的主要文件。
这些结果表明，在等待烟草控制社区进行检索、索引和文件存储而带来的更好的获取机会时，研究人员可以依赖行业网站。搜索烟草行业网站至少与在明尼苏达州进行搜索一样好，并且在某些情况下实际上可能更好。然而，四个较小的子文件集只能在明尼苏达州手动检索。
