Arcanum Digital Science Repository (Arcanum Digitheca) / ADT Plus 

The database is one of the biggest online collection of Hungarikums of 19th-20th centuries; it is an important scientific and source database of Hungarian cultural, social and economic history, steadily enlarging  and accessible via Internet.   

Digital contents are stored and shown in PDF format, so users can see the authentic page image (view) of the original document. 

It provides the service of full-text search, so you can acquire the required information conveniently. 

Search and the list of hits can be narrowed to show a publication, subject or year.  

Boolean operators can be used for searching more words, as a complex search, and INDEX function can also be used; it shows the list of all words of the database. 

The result of search can be seen in a list of hits, together with short contexts, the hits are highlighted in the text. 

It is important to mention that the exact page references are always available, so  paper-based version can be replaced well by digital text in every respect. 

It is available in all libraries of our system;  it is NOT available by remote access, neither for those who have a membership card authorizing to borrow.
