The Electronic Periodicals Archive and Database (EPA) is an archive and registry collecting and distributing the content and data of Hungarian e-periodicals. On the one hand, the EPA is the separate collection for e-periodicals of the Hungarian National Library OSZK), and on the other hand it is a national catalogue of online resources.
The EPA, as a service of the OSZK is charged with the following responsibilities:
The Electronic Periodicals Archive and Database is built on the following three levels:

3.3. The structure of the EPA-archive:
3.4. The online formats used in the EPA :

3.5. We modify the absolute hyperlinks and remove all external references, advertisements, counters, banners.
3.6. The individual issues are available from the "Holdings" link on the expandpage of each archived resource. The holdings page shows available issues in reverse order (newest updates on the top) with issue numbering and publication dates, and sometimes complementary comments about content and format.
The online contents of each isse can be opened from this page.

4.2. The EPA creates a concise bibliographic description for each of the periodicals within its scope, and makes the descriptions available both for web-users and for data-providing systems.
4.3 The EPA is responsible for regular updates on the descriptive data.
4.4 The content of the database is searchable through multiple data retrieval options provided on the user interface of the service and programmed interfaces, created on demand for other databases.
4.5 The periodicals are represented with an uniform "expand" page in the service, with further options depending on the availability of the publication.
5.1. The future third stage of the EPA is an article-database, based on the archived periodicals, enabling information retrieval on the individual articles of periodicals. As a first step of this project, we extracted in XML-format the analytic data of 68 periodical-archives with the support of the Hungarian TOC-Database. The XML-HTML conversion of the data and the building of the searchable database is underway.
6.1. The EPA is responsible for documenting its experiences with the archiving of e-periodicals in the format of public guidelines.
The EPA also produced an extensive TEI DTD applicable to the electronic publication of periodical articles.
