Glossary

Term or Acronym	Description
Accounting code	A reference number used to identify a vendor in an external payment system.
Acquisition unit	An additional layer you can add to acquisitions records that restricts a user’s ability to interact with those records unless they have been assigned to that unit. For example, you may create acquisition units to represent the different libraries within your library system. Units are defined and determined by your library in the Settings app.
Allocated fund	A fund that has been assigned a monetary value for the fiscal year and therefore has money to spend.
Availability	The status of an item in terms of circulation (for example, available; recently returned). In FOLIO, "Item Status" displays availability.
Batch group	Invoices grouped together for export to an external accounts payable system. Invoices from the same library are generally processed together, as determined by the batch group assignment on each invoice.
Bound-with	Multiple, separate bibliographic titles that are bound together in a single volume, most frequently by a former owner but also sometimes by a publisher and for other reasons.
Budget	A finance record that describes the amount of money available for a fiscal year within a fund that includes a definition of the allowed expenditure percentage and allowed encumbrance percentage. Transfers and allocations transactions are performed against a budget. Expense classes can be assigned to a budget.
Bug	An error, fault or flaw in a software system.
Campus	The second level of the four level location structure (Institution -> Campus -> Library -> Location). The structure is hierarchical - a campus must be linked to one institution, and a library must be linked to one campus.
Child record	Associated with linking bound-withs, which allows for "links" between separate bibliographic records and/or a bibliographic record and items belonging to another bibliographic record. Child records are those associated bibliographic records.
CQL	Contextual Query Language. A formal language for representing queries to Information Retrieval systems such as web indexes, bibliographic catalogues and museum collection information.
CRUD	Create, Read, Update, Delete. The basic actions that can be taken on a record in a software system.

Effective call number (item), eye readable	A way of presenting the call number that may be easier for a human being to read.
Effective call number (item), normalized	A standardized way of presenting the call number that may be harder for a human being to read, but easier for a machine to process.
Expense class	A fiscal entity used to track transactions against a specific purpose or function within a Fund.
Item effective location	FOLIO has permanent and temporary location fields on the Holdings and Items records. There is built-in logic for FOLIO to compute the item's "effective location" based on what values are set.
eHoldings	Contains information such as the resource’s URL, call number, etc to enable staff to locate and manage library electronic holdings.
Encumbrance	An amount of money that the library commits to pay to a vendor from a fund budget for ordered materials that will be invoiced in the future.

Fee/fine	Charges attached to patron records for reasons such as damaged materials, late item returns, or rental fees.
Fiscal year	The twelve-month period a library uses to manage its finances.
FOLIO	Future of Libraries is Open. An open-source collaboration of libraries, developers and vendors building an open source library services platform. It supports traditional resource management functionality and can be extended into other institutional areas.
Fund	A fiscal entity used to track transactions against a general purpose or function' within a ledger. Funds are associated with only one ledger. Fund information persists from year to year as new budgets are created for the fund each year.
FYRO	Fiscal year roll-over. After ordering and invoice processing is completed for the fiscal year, a library performs fiscal year roll-over processes to open new fiscal year budgets, close budgets from the prior fiscal year, and create encumbrance transactions in the new fiscal year.
Group	A collection of one or more funds grouped together. A group can bring multiple funds together regardless of fiscal year and ledger which enables the total amount of money available or allocated across multiple funds to be analyzed.
Hidden permission	A permission that you do not see in the list of permissions to assign to users. Hidden permissions are generally very granular permissions that are bundled together in larger permissions sets that are then made viewable to assign to users.
Holdings	A data record that contains information such as location, call number, and volumes owned, to enable staff to locate and manage library holdings. Holdings records may describe library holdings that are physical, electronic, or other formats.

LDP	Library Data Platform. A project that develops an open-source analytics platform (Library Data Platform ) which can be utilized by FOLIO reporting (GitHub - folio-org/folio-analytics: Community query repository for FOLIO analytics based on Metadb/LDP ) for statistical and operational analytics. The term, "LDP," is sometimes also used as a shorthand for a specific component of the platform, such as the LDP database or the LDP query builder app which runs in FOLIO.

Parent record	The main link in a bound-with situation: It will have an item record (and thus barcode) that all other bibliographic records associated with a given bound-with volume can link to. Child records are those associated bibliographic records. Child records will have LKR fields in the bibliographic record that include the ADM number of the parent record and "Enum. Level.1" information found in the parent record's item record. Doing this allows all item record information in the parent record to display in the child record, so the same barcode, sublibrary, collection, description, call number, etc. will show up for all titles in a bound-with.
Patron blocks	Optional limits that libraries can impose on patron circulation privileges, removing privileges when the limits are exceeded. For example, a library can say that if a patron has five lost items, they can no longer borrow books until that number is reduced to four lost items or fewer.
