Why does a library only have a few copies of an ebook?

Because the library did not buy a file, it licensed the right to lend one copy at a time. The limit is contractual rather than technical: a file could be copied indefinitely, and the licence is what stops it. Lending more copies at once means buying more licences.

Why do library ebooks expire and disappear from my device?

Digital rights management enforces the loan period by making the file unreadable when it ends. It exists because nothing else about a file returns it. The side effect is that the book vanishes rather than being handed back, which readers consistently find more abrupt than a due date on a paper book.

Does a library own the ebooks it lends?

Usually not. Most library ebooks are licensed for a period or a number of loans, after which the title is gone unless the licence is renewed. This is the single largest difference from print, where a purchased book stays on the shelf until it falls apart, and it is why long-term digital collections are built differently.

A History of Ebooks in Libraries

Library ebook lending looks strange until you know how it was assembled. A file that could be copied a million times is lent to one person at a time, for a fixed period, after which it stops working. There is a queue for something that is not scarce. The library frequently does not own what it is lending.

None of that is an accident or an oversight. Each part was negotiated, and the sequence explains the result.

Before the devices

Electronic books predate e-readers by decades. Project Gutenberg began transcribing public-domain texts in 1971, and by the 1990s libraries held CD-ROM reference works, early full-text databases and scholarly ebook collections bought on institutional subscription.

That last category matters, because academic libraries had been licensing rather than buying digital content for years before public libraries met the question. The terms — access for a period, access for a number of users, no residual copy when the contract ends — were already normal in one part of the profession when they arrived as a shock in another.

The readers arrive

Dedicated reading devices reached the general market in the mid-2000s. Sony’s Librié appeared in Japan in 2004 and the Sony Reader in the United States in 2006, both using electronic paper, which held a page without drawing power and could be read in daylight.

The Amazon Kindle followed in November 2007, and the difference was not the screen. It was the shop. A Kindle came with a wireless connection to a catalogue, one-click purchasing and no computer in the middle. Buying a book became faster than walking to a shelf, and the reading device became the retail end of a store.

Libraries were not part of that arrangement, and spent the following decade working out how to be.

What a library ebook loan actually is

The model that emerged, and still dominates, is one copy, one user. The library licenses the right to lend a title to one reader at a time. Other readers queue. When the loan ends, the file stops working and the next person in the queue is notified.

The limitation is legal, not technical, and it was the price of getting publishers to supply libraries at all. It preserves the shape of print lending — scarcity, a queue, a due date — in a medium that has none of those properties naturally.

Licences come in several forms: a fixed number of loans, a fixed period of years, or a metered combination. What almost none of them include is ownership. A library that stops paying generally stops having the book, which is the difference that matters most for collections built to last, and one of the reasons What Is a Digital Library? treats preservation and access as separate problems.

DRM, and why the book vanishes

Digital rights management is what enforces the loan. It ties the file to an account and an application, and makes it unreadable when the period ends.

It is also the source of most complaints. A reader who has not finished a book finds it gone rather than overdue. The file will not open in the application they prefer. Accessibility features are sometimes blocked by the protection rather than by the publisher’s intent. And a book borrowed from two different services arrives in two different apps.

The trade was made deliberately. Without an enforcement mechanism, publishers would not license to libraries; with one, lending works but feels less like borrowing than like renting.

Price, and the argument that keeps recurring

Library ebook licences typically cost several times the consumer price of the same title, and expire. Publishers argue that a library copy serves many readers and that frictionless lending substitutes for sales. Libraries argue that they are paying repeatedly for something they used to buy once, out of budgets that have not grown to match.

The dispute surfaces periodically. In 2019 one major publisher restricted library ebook lending of new titles to a single copy for the first eight weeks, and withdrew the policy the following year after sustained objection. Nothing structural changed, and the underlying disagreement is unresolved.

The platforms in between

Most public libraries do not run their own ebook lending. They buy access through an intermediary that holds the catalogue, the licences, the application and the reader’s account.

That is efficient and it concentrates dependency. The reading experience, the available titles and the usage data all sit with a supplier rather than with the library, which is a version of the platform problem described in The Modern Library and one reason consortium purchasing has become the normal defence.

Audiobooks travelled the same route and are now a large share of digital lending, in some services larger than ebooks.

Where it stands, and what is being tried

Three alternatives to the dominant model are in use or under argument.

Simultaneous-use licences, where a title has no queue, generally cost more and suit reading lists and book groups.

Open and public-domain collections, which have no licence problem at all and are the part of a digital collection a library can genuinely promise to keep.

Controlled digital lending, in which a library digitises a print copy it owns and lends the scan one user at a time. Its legal status is contested, and litigation in the United States has gone against the broadest version of it.

What has not changed is the underlying question, which is the same one the profession was arguing about when the first e-readers appeared: whether a library is buying a book or renting access to one. Reading habits themselves moved in the meantime, a subject taken up in Do People Read Differently on Screens?, and the weekly record of the argument as it happened survives in the Library Web Newsletter Archive, 2007–2011.
