Source-derived summary

The Expanded Books Project was a project by The Voyager Company during 1991, that investigated how a book could be presented on a computer screen in a way that would be both familiar and useful to regular book readers. The project focused on perfecting font choice, font size, line spacing, margin notes, book marks, and other publishing details to work in digital format.

Much of the impetus for Expanded Books derived from a meeting on digital books that Voyager sponsored on Bloomsday in 1990, attended by various pioneering multimedia and hypertext experts. Voyager had earlier released a successful CD companion to Beethoven's Symphony No. 9, and its president Bob Stein had obtained a grant to work on creating a similar product for literature. At this meeting, a consensus emerged that, to overcome the relative inconvenience of being tied to a low-resolution and cumbersome digital display, digital books would have to offer "added value". Florian Brody, head of the Expanded Books project, had the idea to design digital books specifically for the then-new Apple PowerBook 100, which Apple had donated to Voyager.

The programming for the initial products took place between October and December 1991. The first three book titles (The Complete Hitch Hiker's Guide to the Galaxy, The Complete Annotated Alice, and Jurassic Park) were released at MacWorld San Francisco in January 1992. These books and their successors relied on a "book engine" that provided a simple but powerful feature set: convenient and simple search methods, the ability to switch between large print and normal print versions, unobtrusive navigation tools (such as a chapter menu that dropped down from the chapter heading on each "page"), a margin area on each page in which readers could write notes, and interactive annotations.

Editorial summary

Begin with the source’s own compact description: “Expanded Books” is open-knowledge reference entry. The dossier treats that line as a proposition to test through Expanded, Books and Open-knowledge, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1991, 1990, 1992—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Expanded, Books and Open-knowledge is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q5420746. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991, 1990 and 1992.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
