The E-Instance and E-Instance Editor are intended to support electronic resources. The E-Instance (also sometimes called EHoldings) stands on its own; it does not have any associated item records. Instead, it combines some information from both OLE holdings and item records into a single record and adds other fields that are useful for managing electronic resources. A bibliographic record may have zero, one, or many E-Instance records associated with and subordinate to it, in addition to OLE Instances. An E-Instance can also be linked to an E-Resource record to represent its participation in a larger electronic resource package. E-Instances can be created automatically when bibliographic records are imported or manually using the E-Instance editor.

A user can create E-Instance records to store and view data about individual titles that make up an E-Resource purchase. The E-Instance record stores data that is unique to the title level, such as URL, coverage dates, and post-cancellation access dates. The E-Instance also inherits data from its parent E-Resource record. In some cases, however, this inherited data could vary and will require customization at the E-Instance level.

Because E-Instance records do not exist independently within OLE but are always linked to bibliographic records, the E-Instance Editor is most often invoked from the display of a particular bibliographic record.  However, it is possible to search EHoldings records separately from bibliographic records, and thus invoke the E-Instance Editor that way.  The E-Instance Editor is not directly accessible from the OLE main menu.

Users may create an E-Instance from two different locations.

Navigation among the Bibliographic record, OLE Instances (holdings and items) and E-Instances is done by means of the links provided in the left pane. For a given bibliographic record, this menu will appear on the Bibliographic Editor screen, the Instance Editor (Holdings) screen, the Instance Editor (Item) screen, and the E-Instance Editor screen. The complete list of holdings, items, and E-Instances associated with the bibliographic record is always available from the left pane regardless of which screen you are viewing

In the left pane, an E-Instance record is shown at the same level as a holdings record. It is identified by Location and E-Resource name elements in the E-Instance record. Not all of these data elements may be present. If neither of them are present, the E-Instance record will be identified by the word “eHoldings” in the left pane until you add a Location or link it to an E-Resource and save it by clicking on the “Save” button.

Click the second top level plus sign to attach a new E-Instance EHoldings record to a bibliographic record in the Bib/Instance Editor. Hover over either of the two "+" signs to see a pop-up note identifying which creates an Instance verses an E-Instance. When creating a new E-Instance, the ‘eHoldings’ label will appear in the left pane after clicking Save if you do not add a Location field and the E-Instance is not linked to an E-Resource.

Right click on the call number to delete an Instance or E-Instance record or add an item record.

If you delete the E-Instance, it will be removed immediately without requiring any confirmation. You can also select the E-Instance in the left pane and click the Delete button in the E-Instance Editor. This will also delete the E-Instance immediately without requiring confirmation.

Click the top level to delete the current bibliographic record. You will be asked to confirm that you actually want to delete the record before you may proceed. If you do not wish to delete the record, click on “Cancel”; you will then be returned to the OLE Describe menu instead of the record you have been working on.

Note

Although you will still be viewing the E-Instance in the editor, if you navigate away from it you will find it has been fully deleted.

Note

In future releases, you will receive an error message if you attempt to delete an EInstance that is linked to a PO.

You can hide the entire left pane from the screen display by clicking on the "Collapse Navigation" command at the top of the pane. To restore the left pane, click on the double right arrows (>>).

The EHoldings ID is a system generated identification number.

The E-Instance EHoldings record includes these tabs -- Overview, Location Information, Call Number Information, Extent of Ownership, Relationships, Acquisition Information, Access Information, License Details, and Note.

The Overview tab contains a summary of critical information about the E-Instance.

In OLE 1.5, the ISSN cannot be filled in.

Platform

The name of the electronic title’s platform. For example "JSTOR." In a future release, this will link to an existing Platform record in OLE.

Publisher The name of the electronic title’s publisher. For example "Elsevier". In a future release, this will link to an existing Organization record in OLE.
Statistical Code

Locally defined value to be used in searching for/limiting searches for items and for statistical reporting. Possible values for this field are the same as for the item record Statistical Searching Code.

Note

If no Statistical Code has been set on the E-Instance and the E-Instance is tied to an E-Resource, the Statistical Code set on the E-Resource will display here.

The Location Information tab includes locations set up at each institution to describe where a resource is available or otherwise categorize it for searching / reporting / display purposes.

The Extent of Ownership tab contains the coverage and perpetual access start and end dates and issues for institutions. It is stored as specific dates, volumes, and issues, rather than as textual summary holdings, to allow for data that could be utilized by a link resolver in the future. There can be multiple Coverage dates and multiple Perpetual Access dates for a single E-Instance.

Click to add Coverage or Perpetual Access lines. Click Remove to remove an existing Coverage or Perpetual Access line.
