Walk into any academic or research library and you will notice two very different kinds of material on the shelves. Some are books that arrive once, get catalogued, and stay put. Others keep arriving issue after issue, year after year, and never really “finish.” These never-ending publications are called serials, and managing them is one of the most demanding jobs in any library. A book is a one-time purchase, but a serial is a long-term commitment that involves budgeting, renewals, claiming missing issues, and increasingly, negotiating digital licenses. This post explains what serials are, how libraries acquire them, the challenges that come with the territory, and how electronic journals have reshaped the entire process.

What are serials?
A serial is a publication issued in successive parts, usually bearing numerical or chronological designation, and intended to be continued indefinitely. This definition comes from cataloguing standards like the Anglo-American Cataloguing Rules and is widely accepted in library science. The key phrase here is “continued indefinitely.” Unlike a book, a serial has no planned ending.
Serials cover a broad family of publications. These include scholarly journals, popular magazines, daily newspapers, annual reports, yearbooks, proceedings and transactions of societies, and numbered monographic series. The word periodical is often used as a near-synonym, but it is slightly narrower. A periodical is a serial that appears at regular, predictable intervals, such as a weekly, monthly, or quarterly journal. A newspaper is a periodical; an irregular conference proceeding is a serial but not strictly a periodical.
Serials versus monographs
The clearest way to understand serials is to contrast them with monographs. A monograph is a complete work in itself, like a textbook or a single research book. When a library buys a monograph, the work is essentially over after acquisition, cataloguing, and shelving. Serials behave very differently. Because they are published repeatedly over time, libraries must manage subscriptions, monitor the regular receipt of issues, and handle delays or missing numbers. This makes serials management far more time-consuming and operationally demanding than handling books.
There are two more important distinctions. First, serials demand a different kind of budgeting. A book is a single payment, while a serial is a recurring expense that must be tracked and renewed every year. Second, serials are valued for their currency. Peer-reviewed journals carry cutting-edge research that books may take years to reflect, which is why research libraries treat journal subscriptions as a core priority.
Methods of acquiring serials
Acquiring serials is not as simple as placing an order. Libraries must choose the right channels, evaluate titles against user needs, negotiate terms, and stay within budget. Several acquisition methods are used, often in combination.
Direct subscription from publishers
The most straightforward method is a direct subscription. The library enters into an agreement with a publisher that outlines the frequency of issues, the subscription period, pricing, and delivery arrangements. Issues then arrive directly from the publisher in print or digital form. This works well when a library needs only a handful of titles from a particular publisher, but it becomes unmanageable when hundreds of journals come from dozens of different publishers.
Subscription agents and vendors
To avoid dealing with many publishers separately, most libraries work with subscription agents or vendors. These intermediaries already have established relationships with publishers and handle negotiation of terms, coordination of renewals, payment processing, and claims for missing issues. A library can place a single consolidated order with one agent and receive a single invoice, which dramatically simplifies record-keeping. Agents may charge a service fee, but the time saved usually justifies the cost.
Consortium access
One of the most significant developments in serial acquisition is the consortium model. A consortium is a group of libraries that bands together to negotiate and subscribe collectively, gaining better prices and broader access than any single library could secure alone. The logic is simple: no single library can collect everything its users need, and group purchasing yields large savings.
The leading example is the UGC-INFONET Digital Library Consortium, launched in 2004 by the University Grants Commission and implemented by the INFLIBNET Centre. It provided access to thousands of scholarly e-journals and databases to member universities, free of subscription cost to those institutions. Its college-level extension, N-LIST, and the broader programme were later merged into e-ShodhSindhu, which offered access to thousands of full-text journals and e-books to universities, colleges, and centrally funded technical institutions.
The most ambitious step in this direction is the One Nation One Subscription (ONOS) scheme, which became operational on 1 January 2025. Approved by the Union Cabinet as a Central Sector Scheme, ONOS centrally negotiates, funds, and provides access to e-journals with INFLIBNET as the implementing agency. The government allocated โน6,000 crore for three years from 2025 to 2027. In its first phase, ONOS provides access to over 13,000 journals from 30 international publishers to more than 6,300 government institutions, reaching an estimated 1.8 crore students, faculty, and researchers, including those in tier-2 and tier-3 cities. This represents the consortium model scaled up to a national level.
Document delivery and interlibrary loan
No library can subscribe to everything, so when a user needs an article from a journal the library does not hold, document delivery and interlibrary loan (ILL) step in. ILL is one of the oldest forms of library cooperation, built on the principle of resource sharing. A user first identifies the required article from a bibliographic or citation database, and then the library obtains the full text from a network member on demand. This article-level, demand-based fulfillment lets libraries meet occasional needs without committing to expensive full subscriptions, and it reduces wasteful duplication across a network.
Challenges in serial acquisition
Serial acquisition is full of complications that monograph purchasing simply does not have. Some are administrative, others financial, and many are legal.
The serials crisis and rising prices
The biggest challenge has a name: the serials crisis. This term describes how subscription costs, especially for scholarly journals, have risen much faster than inflation for decades while library budgets stayed static or shrank in real terms. As a result, libraries are repeatedly forced to cancel subscriptions just to afford the renewals they keep. Much of this pressure traces back to the dominance of a small number of commercial publishers whose journals, especially in science, technology, and medicine, are far more expensive than those of academic societies.
The crisis has knock-on effects across the whole budget. Money diverted to keep costly core science journals leaves less for cheaper humanities titles and for monographs, distorting the entire collection. For libraries in India and other developing countries, the problem is worse because subscriptions are usually priced in foreign currency, so currency fluctuations and exchange-rate volatility add another layer of unpredictability to budgeting.
Changing titles and irregular publication
Serials are notoriously unstable in their identity. A journal may change its title, split into two, merge with another, or change its publisher partway through its run. Each change creates cataloguing and record-keeping headaches because the library must link the old and new titles so users can trace the full history. On top of this, irregularity and variability are inherent to serial publications. Issues may arrive late, out of sequence, or not at all, forcing staff to file claims and chase missing numbers continually.
Licensing terms and access
With electronic serials, the library no longer simply owns a physical copy. Instead it licenses access under a legal agreement. The library must negotiate licensing terms that specify how many users may access the content, the length of the license period, and any usage restrictions. This raises difficult questions about long-term access. If a library cancels a subscription, does it lose all the back issues it paid for during the subscription years? Print journals stay on the shelf forever; licensed digital content can vanish. This is why archiving and perpetual access clauses are so heavily negotiated. Access also depends on technology such as IP authentication or login credentials, which must be maintained correctly so that only authorized users get in.
Role of electronic journals
Electronic journals have transformed serial acquisition from a paper-handling task into a licensing and access-management discipline. They allow instant, simultaneous, location-independent access, which is precisely why national schemes deliver content through digital platforms rather than print.
Aggregators and databases
Managing hundreds of individual e-journal subscriptions one by one would be impossible, so libraries rely on aggregators. These platforms pull together content from many publishers and offer it through a single subscription and a single point of access. Well-known examples include JSTOR, ScienceDirect, SpringerLink, and Project MUSE, along with database providers such as ProQuest and EBSCOhost. Aggregators let a library offer thousands of journals across disciplines while saving the staff time that individual subscriptions would consume.
One catch with aggregator databases is the embargo period. Many platforms delay hosting the most current content of a journal for several months to protect the publisher’s direct subscription revenue. This means the cheaper aggregated access may not include the very latest issues, which can be a problem for researchers who need the newest findings.
Free and open-access periodical services
Not all electronic content carries a price tag. Open-access journals and free periodical services make scholarly content available without subscription, easing the financial burden on libraries. Directories of open-access journals and free archives like PubMed Central give users legitimate routes to full text. However, free services come with a limitation. Open-access journals still represent a relatively small portion of the overall academic journal landscape and may not match the depth or breadth of paid collections. Schemes like ONOS try to address this from a different angle, setting aside funds to support article processing charges so that Indian authors can publish open access more affordably.
Content acquisition in a hybrid world
Most libraries today operate in a hybrid environment, holding some print serials while licensing far more in digital form. Content acquisition now means combining direct subscriptions, agent-managed orders, consortium and national-scheme access, aggregator databases, open-access resources, and document delivery into a single coherent collection. The librarian’s role has shifted from physically receiving issues to negotiating licenses, monitoring usage statistics, managing authentication, and ensuring long-term access. Serial management remains complex, but the tools and cooperative models available today give libraries more ways than ever to stretch limited budgets while meeting their users’ needs.
What do you think? Now that national subscription schemes provide thousands of journals to so many institutions, do you think small standalone subscriptions and document delivery still have a role to play? And how should libraries balance the convenience of aggregator databases against the embargo periods that withhold the most current research?
