2. In order to select the metadata to be imported, click the “Select...” button. The metadata search window will be displayed (see the image below). In that window, the user can select the server and the base to which search queries will be directed. A search query is built on the basis of three values/phrases which are entered by a user in fields on the “Search” panel. The attribute search can be adjusted by a user by selecting appropriate attributes from the expandable lists. In the image below, the attributes selected for the search are “Author”, “Title”, and “Publisher”. In order to start the search, click the “Search” button. Once the search has finished, the results can be viewed with the use of the “Previous” and “Next” buttons, which lead, respectively, to the previous or next page of the search results. The editor can also select a particular page from the search results directly, by means of the expandable list located between the “Previous” and “Next” buttons.

• <name> – this is the server name which is displayed to the editor in the metadata search window; it can be entered for a particular language by using attribute langin attribute lang in the <name> tag; the value of attribute lang should be the two-letter symbol of the language (in accordance with the ISO 639 standard) in which the server name is specified; the default server name is determined in the <name> tag which does not have the lang attribute; Please note that particular names are defined in separate <name> tags.
• <host> – the Internet address of the Z39.50 server (the Internet Protocol address or domain address).
• <port> – the port of the Z39.50 server;
• <user> – the name of the user if the server requires authentication;
