Notes to Reader:
Loan rules in FOLIO are under Apps/Settings/Circulation and then under General and Circulation Rules.
Rules are structured with the criteria first, then a colon, then the policies.
The criteria determine what matches the item to be checked out, the policies determine how long it is checked and the notice, request, and fine and overdue policies:
g undergraduate-student + s TRAIN-RSV-1stFl : l 2-hours-no-renew r holds-pages-and-recalls n notices o no-fines i 48-hour-actual-cost
g undergraduate-student + s TRAIN-RSV-1stFl Is the criteria used to select an item.
Together, the two parts make the loan rule.
The criteria highlight in colors when correctly added. The available ones are:
g Patron group (blue)m Item material type (brown)t item loan type (green)a item institution (green)b item campus (green)c item library (orange)s item location (green)There can be one class of criteria or multiple. Each one needs to have at least one entry:
Multiple criteria are linked by a “+” symbol:
Patrons, material types, and locations can have multiple entries:
FOLIO looks for a match of one each, so these four would match:
Criteria can have all entries selected such as:
For all patron groups. Similarly, a “!” negates an entry such as :
For all material types except reserve. You can mix negated and allowed criteria such as:
Disallows audiobooks but allows audio CD's
Disallows allows undergrad and grad students but allows others as they are not explicitly denied.
Allows faculty and staff but disallows undergrads. (These can be useful in some circumstances but in most cases leaving out an element is more practical.)
Loan Policies always need the same five elements:
All will be colored purple when correct, and if they are correct, they will not need a “+” between each element:
If you have a circumstance where a patron isn't charged fees, fines, or receiving notices, the policy still needs to be present but will need to use a policy set for no action:
Criteria have a default priority listing: priority: t, s, c, b, a, m, g
This means that if there are otherwise identical loan rules that could match, it selects the criteria that matches first. For example t (loan type) is listed before (s) shelving location. If there are two loan rules, one for the stacks location, and one for the loan type of “can circulate,” it will look at the loan type rule first, then go to stacks if no match.
Each table will have a Fallback Policy, what to do if there is no match found. This is almost always a noncirculating policy:
Notice, overdue and fine policies can be added for circumstances where a checkout is overridden, but in typical use would be left as is.
Entering a # or / at the start of a line turns it into a comment. This is useful and encouraged for notes and stating what a loan rule is expected to do:
Most rules are entered as one set of criteria.
Nesting can allow one set of criteria to match multiple possible policies, based upon a first line and then indented lines beneath it. For example:
s NewBooks + t can-circulate
g staff : l 28 day r holds-pages-and-recalls n 10 day notices o no-fines i staff billing
g faculty : l semester r holds-and-pages n semester notices o no-fines i faculty billing
A book that is in the NewBooks shelving location with a loan type of “can circulate” will check out to staff for 28 days with their billing cycle, and faculty for a semester with a separate billing cycle
Nesting can make a more compact loan table but is also harder to diagnose if there are issues. Both nested and single line entries can be in the same table, it's a library's preference if they want to use them.
By clicking at the top, holding the mouse button and dragging down, the entire table can be selected and the copied with Control + C and saved as text file as a backup.
Rules are edited similar to a text file, by selecting a single letter representing a class of criteria or policy, and then a menu of available options to select to select.
In this example “g" is selected to bring up a list of patrons:


When adding new criteria the menu will require selecting from a list of options, selecting one and then another. In this example:

Emeritus faculty has been added and graduate student is about to be selected. Locations require doing through the Institution, campus, and library. From there one or more can be selected.

Values can also be manually typed in if known, and will highlight in color when valid.
If FOLIO detects an error it will highlight in red and indicate where it sees the problem:

In this case a “+” is present after the shelving location but no additional criteria.
Black text means an error or issue:

Here a patron group was deleted at some point, and the UUID is showing. While not harming the table, it should be deleted.
In this example:

The “music cd” material type was manually typed in and is missing the “-” to be valid, whole the loan type does not have a space between the criteria and entry.
If all is good a green message appears:

If an item is showing as non-circulating but it is still checking out, or it is checking out under the wrong loan rule, please note the following:
From the tope of the table down check to see where all would match, or if only a few matches, where the others are not excluded. If you find where the issue is, a new rule can be created or an existing one updated. In the case of multiple matches the rules that are incorrect would need to be edited. If all looks correct the problem may not be in the loan rule table.
