Diogo Barbosa Machado (1682-1772), abbot of Santo Adrião de Sever, occupies a prominent place in the history of Portuguese books, above all because he was the author of the “Bibliotheca Lusitana”, the first Portuguese general bibliography. A scholarly bibliographer and bibliophile, he gathered an extensive and important private library that he would donate to the Crown following the destruction of the Royal Library in the fire that followed the 1755 earthquake.

The collation of each volume is as follows: I - [80], 767, [1 br.] p.; II - [4], 926, [1, 1 br.] p.; III - [4], 798, [1, 1 br.] p.; [8], 721, [4, 1 br.] p.
