An aspect which continues to interest very much is not only the “simplicity” of living together, (at the beginning of the new “order of the monks of Minori Cappuccini) but also the experience of the hermits of Albacina ( where the first monks would meet), anche the charity towards handicapped or sick people, the development of the mission preaches or in the evangelization of the unfaithful, as much as the intellectual and literary development in the Riforma Cappuccina (reform of Cappuccini), almost accompanyng and in a way even before the Concilio of Trento.
Returning to the origins, to a poor life, could not in any way atrophize the activity of the mind or the beauty of thought, because it was not considered simple curiosity of wanting to know, but as service.
The necessity of intellectual preparation stimulated the Cappuccini in giving primary importance to every convent in buying books and in a appropriate place to keep them.
The library was the only place that poverty was not know for the Cappuccini.
These books were also kept in Sulmona, in the Convent of S. Francesco di Paola, not withstanding the various factors that made the monks move from the Convent of the Incoronata to the one of San Giovanni Battista, to the actual one.
Due to the above mentioned factors, the library has 5.000 volumes, including precious manuscripts and books that dated from the beginning of the years 600 - 700, the famous Cinquecentine or Seicentine (refer: books).
Currently, there are numerous autographic manuscripts, which are in the phase of beginning transcribed and publications in the respective critical editions, of the Saint Cappuccino Giuseppe da Leonessa (1556-1612). After the relics ex ossibus of San Giuseppe da Leonessa canonized in the 1746 the most precious are without a doubt, his manuscripts.
Worthy of worship for their origins, from the hands of a Saint, there are of a singular importance due to the part that the words of the Saint, the live of the spirit, can still be heard today in the sheets, which immediately revel more than any other testimony, the private thoughts of the energetic popular preacher.
