    Summon: Library Catalog Deletes

    • Product: Summon

    How do we delete records from the Summon Unified Index?

    There are several methods to delete catalog records from the Summon Index: You can include the deletes in your regular MARC updates, you can submit MARC delete records, or you can send us a flat file (text file) with the list of records to be deleted.
    You don't have to use only one method: You can use the regular MARC updates method in combination with either of the other two methods. However, our system cannot process the flat-file deletion method in combination with submitting MARC delete records. Because of this, you need to decide between submitting MARC delete records or submitting flat files.

    Note that if your method of choice is either to submit MARC delete records, or submit flat files, your regular MARC updates will still recognize records marked for deletion (see details in Option 1 below) and such records will be deleted through your regular MARC updates.
    Click the option below to jump to that section on this page:

    Option 1: Include Deletes in MARC Update Records

    Deletions can be batched with your regular MARC updates and placed in the Updates folder on the FTP directory, as long as the records to be deleted are marked with a "d" in the sixth position of the MARC leader field (position LDR/05). By doing this, record deletions can be processed with the updates.
    If you use a different flag, please let us know prior to uploading the files to our FTP Updates folder.
    Your files must be submitted in the correct format. Please see the Exporting Your Records section of this Answer for details.

    Option 2: Submit MARC Delete Records

    Put one or more MARC records per file into the FTP Deletes folder.
    All MARC records placed in the Deletes folder will be deleted regardless of the delete flag.
    Your files must be submitted in the correct format. Please see the Exporting Your Records section of this Answer for details.
    The word "deletes" must be in the file name. Files containing records to be deleted should be named using this convention:
    sourceid-packageid-deletes-`date +%F-%H-%M-%S`.marc

    For example: yourlibrary-catalog-deletes-2011-01-26-13-18-58.mrc
    For example: yourlibrary-catalog-deletes-2011-01-26-13-18-58.marc

    Option 3: Submit a Flat File (Text File)

    If you are unable to provide delete records within the MARC format, you can provide the unique identifiers of records you wish to delete in a simple text file. Follow these three steps:
    1. Please use the Support Portal option to request the flat-file deletions method, because it requires additional configuration on our part.
    2. After we set up the system for flat-file deletions, follow these rules to create your deleted-records text file:
    • The file must only contain the unique identifiers of the records you wish to delete.
    • The file must contain only one record per line.
    • There must be a line break after every unique identifier.
    • The file must not contain extra fields, text, or delimiters (no spaces, pipes, commas or tildes).
    • The file must be UTF-8 encoded.
    • The file name should not include any spaces or special characters.
    • The file name should include the date and time.
    • The file extension should be one of the following:
      .deletes (preferred)
      .txt
      .keys
      .xml
      For example: yourlibrary-catalog-deletes-2012-01-26-13-18-58.deletes
    3. Place the text file into the Deletes folder of your FTP directory.
