Use of catalogue

Our online catalogue contains the description of the documents available in the Metropolitan Ervin Szabó Library and the data of the copies as well as the bibliographic data of all the books published in Hungarian in Hungary between 1964 and 2002. From 2002 onward, our database includes only those books’ bibliographic data that can be found in our library. 

You can choose one of the following options:

Simple and advanced search

You can search the catalogue for a certain work on the basis of either any word of the item that describes the data of the document, or the part of the word (by truncation % or *).
You can search by the following indexes: Author, Title, Keyword / Subject word, Subject field, Publisher, Notation, Location mark, ISBN, ISSN, UDC
In case of ’Simple search’ you can give one criterion; in ’Advanced search’ more than one criteria can be given.
If more entry fields are filled with search terms, you can connect them by Boolean operators (AND, OR, BUT NOT), or you can narrow the list of hits by given filtering criteria (location, language, type ).
Searching the catalogue by the criterion "Only for loan", you can find the list of documents that can be borrowed from any of the locations in the time of searching; this search type is independent of locations.
If a document has more copies in a location, it is displayed with contracted sequential number. In this case, the status column on the right is empty. status info can be opened by the arrow pointing to right. 


You can choose the own databases of the Metropolitan Ervin Szabó Library in "Collection" search field. If you want to search in all, it is worth using the expression „anything”; it is the basic setting. Three collections that can be searched using the own databases of the library are the followings:

  • Budapest-Bibliography / Budapest bibliográfia
  • Budapest Picture Archive / Budapest Képarchívum
  • Bibliography of Literary Works / Irodalmi bibliográfia
  • Bibliography of Sociology / Szociológiai bibliográfia

The selected list of books, studies and articles concerning the Hungarian capital.

Budapest Picture Archive
The database contains the data of interesting visual representations (photos, prints and drawings) – curiosities – concerning town history; they are stored in the Budapest Collection of the Metropolitan Ervin Szabó Library.

The pictures were taken from two sources:

  • The photographic archive of Budapest Collection where more than 200,000 photos are stored;
  • old illustrated publications, books and periodicals preserved in the collection.
Now only the textual information are available in the integrated catalogue of the library. So, it is worth visiting the independent surface of the database where pictures can also be seen.

Bibliography of Literary Works
It has been developed since 1961. It covers nearly 80.000 items of monographies, essays, criticism concerning the authors of fiction and other types of belles lettre.

Bibliography of Sociology
The Central Library of the Metropolitan Ervin Szabó Library is the national resource library in sociology. The Sociology Collection of the library develops the bibliographic database of the literature of Hungarian sociology. The database has been registering (collecting) the bibliography of Hungarian sociology as well as the social sciences of Hungarian relation since 1970. The database called SzocioWeb contains more than 180.000 items in 2016.

Selection of the literature opened up in the bibliography is based on the definition of sociology in the widest sense and on the most expansive sphere of its borderlands. The database registers articles of periodicals, certain works published in volumes of studies, monographies, works in some volumes, copies of thematic periodicals; it is gradually enlarged with full-text contents as well as electronic documents accessible online. The content is opened up by the collection of subject headings of Köztaurusz.

CCL search - search by the common command language

In this type of search, you can use FIND command and the operators of Boole algebra. If you use this type, you need to know index names (AUTH, TITL, PUBL, etc.).

Pl. FIND AUTH "Kodály" AND TITL "folk music"

Our database contains browsing indexes by author, title, keyword and UDC (universal decimal classification).
It is expedient to use the database if you know the exact title and want to know the standardized name form, or you want to search by keywords.
As a result, you can find the standardized name form and the number of the belonging items. The requested element(s) should be assigned to see the exact hit(s); then you can click to "Show select" and you can see the short description of the hit. If you click to "Details", you can see the longer version of description.

If you are interested in all the hits, you can appoint them by click to „Basket” label.
