'''Microsoft Bookshelf''' è stato un pacchetto software introdotto a partire dal [[1987]] come parte del lavoro estensivo di [[Microsoft]] in [[CD-ROM]] promozional-tecnologici distribuiti per [[publishing elettronico]].

La versione originale per [[MS-DOS]] presentava la massiva capacità di storage della tecnologia CD-ROM, ed era eseguita mentre l'utente utilizzava uno dei 13 differenti [[word processor]] che Bookshelf supportava. Le versioni successive furono sviluppate per [[Microsoft Windows|Windows]] e divennero un successo commerciale come parte del marchio ''Microsoft Home''. Spesso era distribuito in bundle con i nuovi [[personal computer]] come alternativa economica alla suite [[Encarta]]. Bookshelf era distribuito in bundle anche con le versioni ''Encarta Deluxe Suite'' e ''Reference Library''.

Also used for Microsoft Stat Pack and Microsoft Small Business Consultant, the Bookshelf was a [[Terminate and Stay Resident]] program that ran alongside a dominant program, unbeknownst to the dominant program. Like Apple's similar [[Hypercard]] reader, Bookshelf engine's files used a single [[compound document]], containing large numbers of subdocuments ("cards" or "articles"). They both differ from current browsers which normally treat each "page" or "article" as a separate file.

Though similar to Apple's [[Hypercard]] reader in many ways, the Bookshelf engine had several key differences. Unlike Hypercard files, Bookshelf files required compilation and complex markup codes. This made the files more difficult to pirate, addressing a key concern of early electronic publishers. Furthermore, Bookshelf's engine was designed to run as fast as possible on slow first-generation [[CD-ROM]] drives, some of which required as much as a half-second to move the drive head. Such hardware constraints made Hypercard impractical for high-capacity CD-ROMs. Bookshelf also had full text searching capability, which made it easy to find needed information.

===Bookshelf 2.0 engine===

Collaborating with [[DuPont]], the Microsoft CD-ROM division developed a [[Windows]] version of its engine for applications as diverse as [[Document management system|document management]], [[online help]], and a CD-ROM [[encyclopedia]]. In a [[skunk works]] project, these developers worked secretly with Multimedia Division developers so that the engine would be usable for more ambitious multimedia applications. Thus they integrated a multimedia [[markup language]], [[full text search]], and extensibility using [[software componentry|software objects]],<ref name=Viewer 2.0>{{cite book|

In 1992, Microsoft started selling the Bookshelf engine to third-party developers, marketing the product as Microsoft Multimedia Viewer. The idea was that such a tool would help a burgeoning growth of CD-ROM titles that would spur demand for Windows. Although the engine had multimedia capabilities that would not be matched by Web browsers until the late 1990s, Microsoft Viewer did not enjoy commercial success as a standalone product. However, Microsoft continued to use the engine for its [[Encarta]] and [[WinHelp]] applications, though the multimedia functions are rarely used in Windows help files.

===Viewer 3.0===

In 1993, the developers who were working on the next generation viewer were moved to the [[Cairo (operating system)|Cairo systems group]] which was charged with delivering [[Bill Gates]]' vision of Information at your fingertips. This advanced browser was a fully componentized application using what are now known as [[Component Object Model]] objects, designed for hypermedia browsing across large networks and whose main competitor was thought to be [[Lotus Notes]]. Long before Netscape appeared, this team, known as the WEB (web enhanced browser) team had already shipped a network capable hypertext browser capable of doing everything that HTML browsers would not be able to do until the turn of the century. Nearly all technologies of Cairo shipped. The WEB browser was not one of them, though it influenced the design of many other common Microsoft technologies.

Like other hypermedia engines of the time, Microsoft like Apple struggled and failed to understand how it could make money directly from a multimedia browser. Long after the internet revolution, companies continue to struggle to understand how to make money directly from multimedia browser technology but seldom succeed.
