Moreniana Library, Conservation library in Florence, Italy

The Moreniana Library occupies rooms of the Palazzo Medici Riccardi, entered from via de' Ginori, and shares the building with the separate Biblioteca Riccardiana. Its core is the collection of canon Domenico Moreni, joined by part of Domenico Maria Manni's library and later acquisitions from Giuseppe Palagi, Emilio Frullani and Giovanni Antonio Pecci. It specialises in the history of Florence and Tuscany.

The library grew from the collections of canon Domenico Moreni, a bibliophile who compiled a reasoned historical bibliography of Tuscany in 1805. Its main holdings combine Moreni's books with part of Domenico Maria Manni's library, which Pietro Bigazzi, an employee of the Accademia della Crusca, bought with his own money to prevent its dispersal; the Provincial Deputation of Florence then acquired it in 1870. Later acquisitions came from scholars and collectors such as Giuseppe Palagi, Emilio Frullani and Giovanni Antonio Pecci. It opened to the public in 1942.

The library's name honours canon Domenico Moreni, whose 1805 Bibliografia storica ragionata della Toscana remains the reference work behind the collection. Its shelves grew from purchases such as the Manni library, bought in 1870 by Pietro Bigazzi with his own money to keep it from being dispersed.

The Moreniana shares the Palazzo Medici Riccardi with the separate Biblioteca Riccardiana, but the two have different opening hours and regulations. Enter from via de' Ginori; the library is managed directly by the Città metropolitana, which also has its historic seat and offices in the palace.

The collection includes rare private manuscripts from scholarly collectors who specialized in Tuscan antiquities and brought these sources together in one place. These manuscripts often provide insights into the personal research interests of their owners and how history was documented.
