Federated searching

Learn how to use Federated Searching in Amlib, which is the ability to search a combination of the local library, neighboring libraries, other libraries, databases, encyclopedias and websites in a single search as required.

Federated Searching is the ability to search a combination of the local library, neighboring libraries, other libraries, databases, encyclopedias and websites in a single search as required.

In Amlib, this possible by either ZSearch (Z39.50) or setting up e-files (for online articles and websites).

Z39.50 is an international information retrieval standard Application Service between computer systems.

Please Note: To access Z39.50 Servers it is necessary to be able to exit through the firewall for the port defined for the server. The default is usually port 210 but some Servers do use other ports (7990 being quite common)

Z39.50 Search

Searches can be done from Z39.50 client in Amlib:

  1. Launch the Amlib client
  2. Go to Main > Catalogue > CatZSearch – the Z39.50 Search window will open
  3. Click the F5 Query button – the Query window will open
  4. Select the Group or Library from the Servers: drop-down listing. The search query allows you to search within several areas by selecting a Server Group from the available Servers: and selecting and combining multiple search terms at once

    Please Note: Server Groups can be set up to include different Library servers (including ALL). This is done from the Catalogue module – select Application > CatZGroups
  5. Select the search term by using the dropdown boxes in the Search Attributes section and type in the search terms – for example: ISBN, Title, Author, Subject or combination of these
  6. Click the OK button when complete
  7. A result list will then display:
  8. Highlight the required items
  9. Click the Import button – the following message will display: Do you wish to import by saving into a marc file and then via the Authority module marc take up option – if so select Yes or alternatively import now directly? (select No) If you import you will not get all the options available in the Authority method
  10. If you click the Yes button:
    1. The following message will appear: Records may now be imported via Authority Module they have been saved in File...
    2. Click the OK button – the Open window will display:
    3. Select the file and click the Open button
    4. Marc take-up will automatically commence - the Marc Import screen will open
    5. Complete import as per standard Marc Import
  11. If you click the No button:
    1. The Import window will open
    2. Enter details in the Tag Actions fields as required – you might like to saved a record of your imported records into a Saved File
    3. Click the OK button – the MARC records will be imported
    4. Once complete you will see the following message: All the selected records have been imported. Stockitems have been refreshed where appropriate
    5. Click the OK button 

The import is now complete.

Please Note: Schools can link to SCIS in this way. You will need to contact SCIS directly to get your IP address authorised and they will supply the details of the SCIS z39.50 details you will need to set them up as a Server to be accessed through Z39.50.

Z39.50 Searching: settings and parameters

CatZServers

Servers are the Libraries or databases you wish to search. F1New enables you to enter new databases to search. A list of accessible Z39.50 target databases in Australia can be found at the following link from the National Library http://www.nla.gov.au/libraries/z3950/z3950list.html

  • Description = the description you will see in Amlib of the Library or database.
  • Display Seq = the order in which you wish the list to display (for example: 1, 2, 3 etc – the number here needs to be unique)
  • Host = the Internet Address of the Library or database. If this is not correct, you cannot be connected to perform a search.
  • Port = TCP/IP port - the most common port number for Z39.50 is 210
  • Server Type is generally Other unless it is an Amlib site
  • Database is the name of the database. This will also need to be supplied by the Library or database being searched.

    • Database: XXDEFAULT
    • Server Contains Holding Data: NO (will not work if set to Yes)

Please Note: You can set up your own Local Library findings in combination with the others if you have purchased ZServer.

ZOpac allows the Public to search across Databases in the same way. For example, check out Armadale’s ZOpac at: http://library.armadale.wa.gov.au/zopacs/
