Release, Issue or Publication Information (Required If Applicable)

These fields are intended to record information on when the object was either issued, released in its original format or actually published. If you have unpublished material, just record either a single date or a date range. If you have published material, then you can record the place of publication and publisher and date the object was published.

Dates: Record either a single date or a date range but not both. You can qualify any of these dates using one of these terms: inferred, questionable, approximate. Dates must be entered using the W3CDTF standard or as YYYY, YYYY-MM or YYYY-MM-DD. Avoid any brackets, question marks or other punctuation which can be expressed by the approximate qualifying term.

Tips for Using the MODS Form


List of Preferred Controlled Vocabularies

Subjects (Topic, Place, Name) and Genre terms should be taken from controlled vocabularies. If the subject term does not have an authorized heading in a controlled vocabulary list, then select “No Controlled Vocabulary Consulted” or for names that do not have an authorized name authority file select “local”.


Adding More Entries to a Field

For subjects, enter one topic, place or name per entry. Use the + sign or the add button to add more than one entry.

There are 2 ways to add an entry:

The + (plus) sign. If you click on this button, you will see that your first entry is now below the field and the entry field is blank as seen in this image. You can remove any of your entries by clicking on the – (minus) sign.

The add button allows you to enter an additional entry. The primary difference between the add button and the plus sign is that the + sign is typically only for single data entry points such as a term or phrase whereas the add button is to add a grouping of information such as a name, which requires a name type and for creators/contributors also a role term.


Removing Information from a Record

There are 3 ways to remove information:

  • You can click on the minus sign.

  • Highlight and remove all of the information in the field then click the "x" next to the number.

     

  • For fields with a single entry, highlight the information and delete it.


Collapsible Sections in the Form

The following sections in the MODS XML forms can be collapsed: title, name, genre, information on origination, physical description, identifiers, subjects (and within that topics, place, name and coordinates).

To collapse a section, click on the arrow, which is either next to the number or just underneath it.
