  values = record.fields('775').filter_map do |field|
    next unless subfield_defined?(field, :i)

    other_edition_value(field, relator_map)

end

.show(record, with_alternate: true) ⇒ Array<String>

Edition values for display on a record page. Field 250 is information relating to the edition of a work as determined by applicable cataloging rules. For mixed materials, field 250 is used to record statements relating to collections that contain versions of works existing in two or more versions (or states) in single or multiple copies (e.g., different drafts of a film script). For continuing resources, this field is not used for sequential edition statements such as 1st- ed. This type of information is contained in field 362 (Dates of Publication and/or Volume Designation). www.loc.gov/marc/bibliographic/bd250.html

Parameters:

  • record (MARC::Record)

Returns:

  • (Array<String>) —

    array of editions and their alternates
