Avaliação comparada do uso de linguagens de indexação em catálogos de bibliotecas universitárias para recuperação por assunto

A comparative evaluation was made of the use of natural language versus two specialized indexing languages, aiming to demonstrate the influence of the availability of indexing languages on the functioning of information retrieval systems. The study was conducted within the ambit of the construction of search strategies by subject in online university library catalogs. The precision ratio was calculated to determine the accuracy of each indexing language in subjectbased information retrieval. From the comparative evaluation of the use of indexing languages, it was concluded that the term specificity required by the user during retrieval was more satisfactory when the query was made through controlled languages, whose availability and simplicity is also an indispensable requisite.

Thaddeus Mason Harris' working documents regarding subject-based library catalog, ca. 1790

Thaddeus Mason Harris, who served as interim librarian of the Harvard College Library in 1787 and as its librarian from 1791 through 1793, is believed to have created these notes while helping compile the library's first printed subject-based catalog. The catalog, Catalogus Bibliothecae Harvardianae Cantabrigiae Nov-Anglorum, was published in 1790 and represented a significant change in approach to the cataloging of the library's collections, which had formerly been cataloged alphabetically. These documents, many of them on small scraps of paper, contain the titles and bibliographic information of books on a range of topics, from "Anatomici" to "Rhetorica."
