Catalog:
Manuscripts and archival materials are integrated in the general catalog; but you may execute your search either in the entire catalog or by typologies; for manuscripts, select "Manuscript and private papers"
Up to now, there are more than 7.000 notices, including medieval and renaissance codexs, XVII-XXth manuscripts and archival materials (over 200 private archives, mainly personal)

Digitised Manuscripts
Documents are accessible through the webpage "Memoria digital de Catalunya"; again, there is a section devoted to manuscripts, that includes up to now 185 documents; the number should be largely increased this year.
