Many special collections enrich the FSCIRE libraries, such as: critical editions both in printed and digital format (COGD and MANSI); synopsis and indexes of the II Vatican Council; digitized manuscripts and ancient books; virtual tools and databases.
The Giuseppe Dossetti Library also preserves the following special collections:
This collection consists of a total of 7,100 volumes, 300 of which originate from the Capuchin Convent of Bologna, where they are held in duplicate. The editions of the works vary from the 17th to the 20th century. It is of considerable antiquarian interest that at least 2000 of these volumes date back to the 17th and 18th century. Furthermore, the collection is enriched by three 16th century editions in good condition.
The library collection of SS. Salvatore in Bologna held in the Dossetti Library is composed of over 2,300 volumes printed between the 16th and the 19th century. They are what remained in the Bolognese complex of SS. Salvatore following the work carried out on the Archiginnasio Municipal Library in 1886. Of these works, 34 are 16th century editions, 110 are 17th century editions, 760 18th century editions and over 1400 are from the 19th. In 2022 the two last collections have started being catalogued.
