125 useable replies were received via the web and 31 by fax or postal service. Respondents using the web to reply had higher self perceived ability to use the Internet, used the web more often, were seven years younger in mean age, but did not differ significantly in years of Internet experience, web access, or gender. Of the 147 who attempted access to the web survey 125 finished successfully. Sixty percent only completed the survey, with the remainder looking only at their own completed results. The non-electronic respondents did not view results.

This article looks at the efficiency of a modification of the inverted file indexing model. In block addressing indexing inverted file entries do not refer to text position within a particular document but rather to predefined blocks of text of the document. Space is saved, but block hits must be scanned sequentially. BaezaYates and Navarro show theoretically, and confirm experimentally using their methods on TREC databases, that both space and time considerations in a block index can be sublinear and, thus, that file growth decreases the relative significance of time and space considerations for the index.
