Managing the Access to Scientific Grey Literature through internet and Free Software

We built threee mid-size databases using some script in Pearl language and three free-version software packages. This system enables full autonation of intranet building/upgrade process with web-dispay of the Grey Literature produced by our Institute. The first database is accessible by local network, the second database is set up via CISIS with the previous database records. The third database contains only the titles and the keywords of the documents recorded in the first database and it is used to show documents related to the searched document. This database is words-indexed by Isearch (CNIDR, 1994). Isearch uses an algorithm of "closeness" thanks to which the related documents are ordered by a "relevance ranking" based on statistical analysis of word frequencies. This system can provide a synergistic online exchange of informations among researchers of the same Institute and increases public trasparency of the grey Literature of the Institute at no additional cost besides the Hardware and operating System costs.
