Center for Research Libraries - Global Resources Network


LAMP (formerly the Latin American Microform Project) at the Center for Research Libraries received funds in 1994 from the Andrew W. Mellon Foundation to explore aspects of digitization from microfilm. Working in cooperation with the Biblioteca Nacional do Rio de Janeiro, LAMP selected its collection of Brazilian government documents because of their scarcity, importance, and volume. Completed in December 2000, the project digitized more than 670,000 page images of government publications, freely available over the Web. Read more in the detailed final report of the project.


The Brazilian documents were scanned from microfilm copies of the originals, which were filmed by the Biblioteca Nacional do Rio de Janeiro. The images are stored as GIF and TIFF images in the Center for Research Libraries’ Electronic Document Storage and Distribution Facility. The GIF images, at a resolution of 100 dots per inch (d.p.i.), are viewable using standard Web browsers. The TIFF 300 d.p.i. images offer greater clarity, but may require a TIFF viewer for use. When GIF images are not legible, click on the “300-d.p.i. TIFF image” link at the top and bottom of each page display.

Image Quality and Selection

The images in this database are uneven in quality. Most images are legible, but some are not. The quality of images can vary considerably from one page to the next. Poor image quality is due to the poor condition of the paper copy when it was filmed. The damaged paper copy resulted in degenerated microfilm images, which then migrated to the electronic medium. In a few isolated cases, such as the entire Piaui Provincial Presidential Reports, the film images were not scannable. Documents not available on film have been considered unavailable and have been omitted from these files. Blank pages included in the original page sequences, which were also copied during microfilming, have not been scanned. The corresponding page numbers for these pages have been dropped from the index.
