The predecessor of the library is the book collection of the Moson County Historical and Archaeological Society found in 1882. Initially the main source of extention was meant by donations. On these early pieces of our collection we can see the label of the society's librery, too.

Before the first world war the book collection consisted of 2000 pieces. Today we have almost 12 000 books and periodicals.

The pride of the museum is the nationally registered collection of old books written on the history of Hungary. We can see such rarities as all the 5 volumes of the 'Notitia Hungariae novae historico-geographia' written by Mátyás Bél. This was presented to the society by earl Jenő Zichy in 1892. Another piece of interest is the work of István Széchényi - minister of transportation - dedicated to the leaders of Moson county.

The collection contains a good number of latin dogmatics written by János Alber Nepomuk. We also have a number of nice numismatic books and series (for instance Cohen catalogue).

The German and French books of the library established by typographer Sándor Czéh (1841) compose an independent collection group. These had been covered by dust in the attic of a house for long.

The individual, handwritten monographs are contained in the supplementary archive of the library (1000 items). One of the most prominent materials is that of the documentation material of 15.000 pieces, which involves a good number of interesting typographical things.
