Although many library staff users have come to use the OPAC level [Issue and return] dialog, the original [Circulations] dialog intended for staff use is available from the [Quick Access] toolbar group on the main workspace, or from the [Staff Menu] toolbar icon.

While the OPAC level [Issue and Return] dialog provides convenient circulations capabilities, the [Circulations] dialog provides far more background power, information, and the real-time ability to see what is being decided upon by the Circulations engine in detail in regards to circulations rules - information which would normally be available to a Reader Assistant in the OPAC system (for which the OPAC Issue and Returns dialog was originally intended) only by investigating a failed circulation.

The [Circulation Dialog] is constructed from four main sections, top to bottom in the dialog area:

• Search Criteria - The two fields in the top section of the dialog allow you to type or scan the barcodes for a reader and an item which will be circulated, or which will have a similar operation performed (see below). This section also contains two drop-down pick-lists which can be used to select a specific reader or item if the search criteria used identifies multiple records.

• Details - The second section of the dialog displays the details of the reader and item as they are identified. Where a row is prefixed by an [▶] arrow, this indicates that further information is available in this group. Click the arrow to expand the row to see the further details.

• Function Details - The third section of the dialog shows the details of the current functional operation in progress - the most common and default being Circulations. The section can be placed into Reservations or Bookings mode by clicking the appropriate section of the multi-select button.

• Command Buttons - The base of the dialog contains the buttons that are used to control the current functional operation selected. In the case of the Circulations function being selected for example, the command buttons will be displayed as [Issue], [ReIssue] and [Return] as and when appropriate.

At the most basic, the Circulations dialog is intended to perform a Circulation - assigning an item in the catalogue to a reader for a set amount of time and using defined rules.

Enter a reader barcode number into the [Reader:] field. The text field provided is a search criteria field. If a unique barcode is entered which can be matched against a single reader, the reader is displayed ready for use. The cursor is automatically placed into the [Item:] field.

Note however, that if a single specific reader is not identified, the information entered into the search criteria field may find other readers that match the entry and are all entered into the drop-down pick-list beneath the search field. The search criteria field need not therefore, only be used for reader barcodes - a reader name or part of one can be entered into the search field instead.

If multiple readers are displayed in the drop-down pick-list, select one from the list to make it the active reader in the current circulations process.

Enter the item accession barcode into the [Item:] field. This field acts in exactly the same way as the [Reader:] field, and performs a search of the catalogue for the accession number or a component of the title. Also in the same way, the search results are placed into the drop-down pick-list beneath the [Item:] search field.

If a single item is found, the details are displayed immediately. If a number of results are found, select the appropriate entry from the drop-down pick-list to make it the current item for the circulations process.

Once a a valid reader and item are selected in the two search fields and their details are displayed, and the item is not already on-loan, you can issue the item by clicking the [Issue] button at the bottom of the dialog.

If the item is on loan to the currently selected reader, you can instead choose to re-issue by clicking the [ReIssue] button instead, which will extend the load duration.

Once a valid item is selected and its details are displayed, and it is on-loan but not to any currently displayed reader, it can be returned by clicking the [Return] button at the bottom of the dialog.

Once details of both a reader and an item are displayed, a calculation is performed by the Circulations dialog to decide if and how the item can be issued to the reader. The Functional Details section of the dialog (the second from last segment) displays three fields which can be modified to alter the way in which the circulation will be made, as well as a list of the rules that will be applied:

• Start Date - The start date is the date on which the circulation will begin. It is therefore the ultimate base value from which all other circulations rules are calculated. It should not normally be modified.

• Duration - This field defaults to [0] and represents the default override to the duration that will be calculated by the circulations rules.

• Due Date - This field allows the staff user to specify the date on which this item should be returned, rather than try to mentally calculate the required duration to use if a specific return date is required.

• Circulations Rules - A list of circulations rules are displayed working down from the base [Start Date]. Each subsequent rule is calculated based upon either a reader detail, item detail or a circulations rule based upon the nature of both.

If any single row in the circulations rules list is displayed in Red, that rule is preventing the circulation from occurring at all. This may be because the reader already has too many items, the item itself is locked, or the circulation would result in the return date being outside the availability of the reader or item.

In order to override the rule preventing the circulation, click the green tick (active) next to the rule to turn it off and temporarily prevent it from being included it in the calculation. Once all rules in the calculation can be successfully applied, the Duration and Due Date fields are modified to display when the circulation will apply until. Click the [Issue] or [ReIssue] button to complete the circulation as normal.

If a reader needs to return an item, but for whatever reason the item is not in the possession of the staff user, it can be returned by selecting the item from the reader details:

• Enter the reader barcode as normal to select and display the Reader Details.

• Click the [▶] button next to the In Possession row to display all items in possession of that reader.

• Double-click the item as it appears in the In Possession list to select that item as the current item in the circulations dialog

• Click the [Return] button to return the item as normal.
