Koha Acquisition Workflow – Important One-Liners

Acquisition Concept

👉 In Koha, the acquisition workflow follows the sequence Budget → Vendor → Basket → Order → Invoice.
👉 This workflow ensures financial accountability and systematic procurement of library materials.
👉 The acquisition module integrates financial control with bibliographic record creation.

Step 1: Budget and Fund Setup

👉 Acquisition begins with creating a Budget for a defined financial period.
👉 Budgets are usually created for annual financial cycles such as 2024–25.
👉 Each budget is divided into Funds representing subject or departmental allocations.
👉 Funds allow controlled spending for specific disciplines or collections.
👉 Planning values can be set to prevent overspending beyond allocated limits.

Step 2: Vendor Management

👉 Vendors are created under Acquisitions → New Vendor.
👉 Vendor records store supplier details such as address, discount terms, and contact information.
👉 Koha supports multi-currency transactions for international vendors.
👉 Vendor profiles can also include tax and GST configurations.

Step 3: Basket Creation

👉 A Basket represents a group of orders sent to a single vendor.
👉 Each basket is usually created for specific departments or purchase periods.
👉 Example: “Science Department Orders – October”.
👉 Baskets simplify order organization and communication with vendors.

Step 4: Adding Orders to a Basket

👉 Orders can be added directly from patron purchase suggestions submitted via OPAC.
👉 New bibliographic records can be created when the library does not already own the title.
👉 Records can also be imported using Z39.50 copy cataloguing from global databases.
👉 Vendors may supply MARC files that can be uploaded as staged records for bulk acquisitions.

👉 Each order must be linked to a specific fund for financial tracking.
👉 The List Price is entered during ordering.
👉 Koha automatically calculates the Actual Cost based on vendor discounts.

Step 5: Closing the Basket

👉 After all orders are added, the basket must be closed to finalize the purchase request.
👉 Koha can generate Purchase Order documents in PDF or CSV format.
👉 These purchase orders are sent to vendors as official order confirmations.

Step 6: Receiving Ordered Items

👉 When books arrive, staff use Receive Shipment under the vendor account.
👉 The Invoice Number and shipping charges are recorded during this step.
👉 Each item is then marked as Received in the system.

👉 During receiving, librarians assign Barcode numbers to individual items.
👉 The Call Number and Item Type are also defined at this stage.
👉 After processing, item status changes from “Ordered” to “Available” or “In Processing.”

Step 7: Invoice Processing and Finalization

👉 Final cost verification occurs during invoice processing.
👉 If the vendor price differs from the original order, the Actual Cost is updated.
👉 Once confirmed, the system marks the budget funds as spent rather than encumbered.

Important Acquisition Terms

👉 Encumbrance refers to funds reserved for orders that are not yet received.
👉 Encumbered funds ensure budget allocation is protected during the purchasing process.

👉 EDIFACT is an electronic data interchange standard used for automated order communication with vendors.

👉 Budget Mapping restricts librarians to specific funds based on their purchasing authority.

👉 TREC provides test collections, queries, and relevance judgments for retrieval research.

👉 Inverse Document Frequency (IDF) is used in TF–IDF weighting to emphasize rare but important terms in documents.
👉 TF–IDF helps search engines rank documents based on relevance to user queries.

👉 Stemming is a process that removes word endings to create a simplified root form.
👉 Example: Studying → Studi.

👉 Lemmatization identifies the dictionary base form of a word using linguistic analysis.
👉 Example: Better → Good.

Rare and Specialized Metadata Schemas

👉 VRA Core is a metadata standard designed for describing visual culture objects such as images, artworks, and architecture.
