Streamlining Processing Tasks in Libraries: From Classification to Shelving

Every book that reaches a library shelf has already travelled through a hidden assembly line. Before a reader can pull a title off the rack, library staff must classify it, catalogue it, label it, and place it in exactly the right spot. This behind-the-scenes work is called processing, and it determines whether a collection of thousands of documents feels like an organised resource or an unsearchable pile. Today much of this work is powered by software, barcodes, and shared bibliographic standards. Understanding how processing has moved from manual registers to automated workflows shows why modern libraries can manage huge collections with small teams.

What library processing actually means 🔗

Processing, often grouped under the broader term technical processing, covers all the technical activities that prepare a document for use. According to teaching material from the INFLIBNET Centre, these activities chiefly include classification, cataloguing, physical processing, shelving, and filing of library material. The goal is simple to state but hard to achieve at scale: every item must be located, used, and returned to its correct place without confusion.

The reason this matters has grown with the sheer volume of published material. As collections expand into the lakhs of titles, no library can rely on memory or rough arrangement. Each document needs a fixed address and a searchable record. Processing is what gives every book that address and that record.

Classification and cataloguing 🔗

Classification and cataloguing are the two intellectual pillars of processing. They are different tasks that work together. Classification decides where a document sits on the shelf. Cataloguing creates the searchable description that helps users find it in the first place.

How classification systems organise knowledge 🔗

Classification groups documents with the same or similar subject content together. As explained in reference sources, the Dewey Decimal Classification (DDC) divides knowledge into ten main classes, each further split into divisions and sections using decimal numbers. A book on Indian history and a book on Mughal architecture end up near each other because their numbers fall in related ranges. DDC is now maintained as WebDewey by OCLC, which provides regular updates so the scheme keeps pace with new subjects.

Many academic and special libraries instead use the Universal Decimal Classification (UDC), which builds on Dewey’s framework but adds symbols that let a cataloguer express complex relationships between subjects. A document about the economics of water management in agriculture can be expressed through combined notation rather than forced into one narrow category. Indian libraries also widely use the Colon Classification developed by S. R. Ranganathan, an analytico-synthetic scheme that constructs class numbers from facets rather than a fixed list.

A key point worth remembering is that classification assigns each work to only one physical place. Reference material notes that a book can have only one shelf location, even when its subject matter touches several fields. This is why the cataloguer must judge the dominant “aboutness” of a document before assigning a call number.

Why cataloguing carries the weight of discovery 🔗

If classification is the address, the catalogue is the directory. Cataloguing produces a structured record describing each item, including author, title, publisher, year, physical details, and subject headings. In the manual era, this meant typing or writing catalogue cards and filing them in long wooden drawers. A single title might need several cards, each filed under author, title, and subject. Maintaining these card catalogues was slow, repetitive, and prone to filing errors.

Computerised cataloguing changed the entire workflow. Instead of physical cards, records are stored in a database and can be searched, edited, and shared instantly. The work of describing a book is done once, and the resulting record serves every type of search at the same time.

The standards that made cataloguing machine-readable 🔗

For computers to read and exchange catalogue records, libraries needed a common format. This is where bibliographic standards became essential.

MARC 21 and the shared language of records 🔗

MARC stands for Machine-Readable Cataloguing, and MARC 21 is its current implementation. Developed and maintained by the Library of Congress, MARC is not a set of cataloguing rules but a format that tells the computer what each piece of information means. Every record carries “signposts” in the form of tags, indicators, and subfields. For example, the tag for title information is different from the tag for the author’s name, so software can display, sort, and search each element correctly.

The real power of MARC 21 is interoperability. Because libraries across the world encode records in the same structure, one library can download a catalogue record created by another and reuse it. This practice, known as copy cataloguing, saves enormous effort. Records are exchanged using the ISO 2709 standard, and INFLIBNET’s training material confirms that modern library software supports copy cataloguing in MARC 21 format through this exchange standard. In the Indian context, the National Library and the Indian National Bibliography have adopted MARC-based practices to keep bibliographic records consistent across institutions.

OPAC as the reader’s window 🔗

The Online Public Access Catalogue (OPAC) is the search interface that readers actually use. Over the past few decades, databases and OPAC systems have gradually replaced card, sheaf, and microform catalogues. A student today searches a library’s holdings from a phone or laptop rather than flipping through drawers.

A modern OPAC does far more than match keywords. It can provide full support for MARC 21 bibliographic, authority, and holdings data, and it can connect to other catalogues through the Z39.50 protocol so a user can search several library databases from a single interface. Many OPACs also link records to digital content such as tables of contents and e-journal homepages, turning a static record into a gateway to full resources. Open-source systems like Koha and the SOUL software developed by INFLIBNET have made these features affordable for Indian college and university libraries.

Automating shelving and labelling 🔗

Once a record exists, the physical item still needs to be prepared and placed. Physical processing includes inspection, stamping a property mark, attaching due-date slips, fixing protective covers, and most importantly, labelling. The spine label carries the call number that matches the classification, and this is what guides both staff and readers to the right shelf.

Barcodes and RFID 🔗

Automated labelling reduces the errors that plague manual systems. In a barcode workflow, each item receives a unique barcode linked to its call number and catalogue record. Staff scan the label during check-in, check-out, and stocktaking, and the system updates the item’s status automatically. This removes the need to copy accession numbers by hand and cuts down recording mistakes.

Radio Frequency Identification (RFID) takes this further. Unlike barcodes, which require line of sight and one-by-one scanning, an RFID reader can capture many tagged items at once. A vendor in the field notes that RFID allows numerous items to be processed immediately without individual alignment, and that the tags resist the wear and tear that often renders barcodes unreadable. RFID also helps protect materials from theft and lets staff track items through every stage of circulation.

Faster, more accurate shelving 🔗

Shelving is where automation quietly delivers its biggest gains. Misshelved books are effectively lost until someone stumbles upon them. RFID-based systems can read an entire shelf in seconds and flag items that are out of order. Patent literature describing library RFID applications explains that a system can build a shelving database automatically as inventory is taken, even guiding staff along a preferred path through the stacks during reshelving. What once took a team several days of manual shelf-reading can be completed in a fraction of the time.

The advantages of automating processing 🔗

Bringing these technologies together transforms how a library operates. The benefits fall into a few clear areas.

Reduced manual labour: Copy cataloguing through MARC 21 means staff no longer recreate records that already exist elsewhere. Automated check-in, check-out, and stocktaking remove hours of repetitive scanning and writing. Smaller teams can manage far larger collections.

Fewer errors: Machine-readable labels and standardised records cut down the misfiled cards, mistyped accession numbers, and misshelved books that slow down retrieval in manual systems.

Quicker retrieval: A searchable OPAC linked to accurate location data means a reader can find whether an item exists, whether it is available, and exactly where it sits, all in one search.

Better use of space: Automated inventory data shows which items move and which sit unused, helping libraries plan shelving, weeding, and storage. Some systems even use item dimensions to optimise placement and make better use of available shelf space.

Taken together, processing has shifted from a slow clerical chore into a streamlined, standards-driven workflow. The intellectual judgement of classification and cataloguing still rests with trained librarians, but the mechanical burden now falls on software, barcodes, and RFID. The result is a library that can grow without collapsing under its own weight.

What do you think? If your college library still relies partly on manual records, which processing task would benefit most from automation first: cataloguing, labelling, or shelving? And as RFID and shared bibliographic data become cheaper, how should the role of the cataloguer change in the years ahead?
