The section of leaflets is not unitary since it collects publications of various kinds, as there are loose leaflets in Varios (Various) and in Referencia (reference).In Varios F, there are 35 boxes of leaflets from the 16th to the 19th centuries, of very different matters: on evildoers, inquisitors, silk manufactures, guilds, Universities, colleges, War of Independence, Italian opera, etc. and plenty of them about legislation.

In the leaflets of the section of Referencia, in addition to the catalogues and bibliographies, there are the rules and guidelines of libraries, archives and museums, etc.

There also exists, a collection of musical scores from the Intellectual Property Registry and the Legal Deposit.
And finally, most of the section is composed of around 1400 boxes that collect the publications from the 19th to 20th centuries.

It should be noted that the term “leaflet” has not to be strictly understood, as in our case, it can be understood as folded sheets or over 100 pages documents.
