The current library holdings of ELTE's public education institutions are available on the common search interface

School libraries belonging to the ELTE library network catalogue their documents in various databases. While maintaining these systems, the ELTE University Library and Archives developed a common search interface in 2011 within the framework of the TÁMOP-3.2.4/09/1/KMR-2010-0021 project, which can be accessed directly at https://gimikatalogus.elte.hu. It is also possible to access the common catalogue of ELTE libraries by clicking on the marked menu item:

The records of the libraries in the database:

• Library of the ELTE Apáczai Csere János Secondary School and College (14 293 records),
• Library of the ELTE Gyertyánffy István Primary School  (26 193 records), 
• Library of ELTE Radnóti Miklós Primary and Secondary School (31 785 records),
• Library of ELTE Trefort Ágoston Secondary School (31 011 records).

The conversion of school library databases is regular. Once a year, usually in November, the data are updated to reflect changes (additions and deletions) from the previous year.
