### Basic editing

To open a record to edit it, just click on its title or the **Edit** button in the search results list (see previous page for guidance on searching).

The record will open in MARC 21 view or text view depending on your user preferences. You can change your display for the record you're viewing under **Record > Change display to Text view/MARC 21 view**.

You can edit fields by typing directly into them.

You can add or delete fields using the green and red plus and minus buttons on the right-hand side.

In MARC 21 view, you can move fields up or down using the arrows on the left-hand side.

If you make a mistake, you can use the undo function under **Edit > Undo:**

To expand fixed fields (e.g. the LDR and 008) in MARC 21 view, click the small grey arrow next to the field:

<figure><img src="/files/sEr5Y8VMI3Yr83eFCgR9" alt=""><figcaption><p>Screenshot showing expanded fixed field editor</p></figcaption></figure>

Clicking the question mark symbol next to the dropdown menus in fixed fields opens the relevant section in [OCLC Bibliographic Formats and Standards](https://www.oclc.org/bibformats/en/about.html).

{% hint style="warning" %}
You can only have one expandable field open at a time. You need to close the field (pressing the small arrow again) before you can expand a different field
{% endhint %}

To add subfields, just type a dollar symbol ($). When you click out of the field, a space will be added before and after the delimeter and subfield.

In MARC 21 view, the 33X fields can be added or changed using a dropdown menu. Click the small grey arrow next to the field and select the appropriate term from the dropdown list. This will automatically populate the subfields:

### Controlled headings

To control a heading, right-click in the field and go to **Controlled headings > Add**:

Suggestions of controlled headings may also appear when you click into a field:

Once you have added a controlled name, you can add a relator term using a dropdown menu. You can open this by clicking the small grey arrow next to the field:

{% hint style="info" %}
You can control both Library of Congress subject headings (LCSH) and Medical Subject Headings (MESH)
{% endhint %}

### Accessing guidance

You can access a number of sources of guidance when editing a field by going to **Edit > Field Help**:

<figure><img src="/files/ojdIBO95P5CQBpFmlObs" alt=""><figcaption><p>Screenshot showing Edit menu and options for accessing MARC Field Tooltip, MARC Field Help and RDA Toolkit</p></figcaption></figure>

**MARC Field Tooltip** opens a brief description of the field you're editing.

**MARC Field Help** opens the relevant section of [OCLC Bibliographic Formats and Standards](https://www.oclc.org/bibformats/en/about.html).

**RDA Toolkit** opens the relevant section of the [original (old style) RDA toolkit](https://original.rdatoolkit.org/).&#x20;

{% hint style="warning" %}
To be able to access RDA Toolkit, you need to have entered your credentials under user preferences. See [Set up](/library-cataloguing/9yMHsFGBXS9DDRGtdmSE/systems-guidance/oclc-worldshare-record-manager/set-up.md) for more information
{% endhint %}

### Finishing a record

Before you can export a record you need to **Validate** the record and **Set WorldCat Holding**. You can do both of these from the **Record** menu:

You can also save the record by going to **Save > Replace Bibliographic Record**:
