The following books and articles provide a good introduction to the blackboard approach and describe its development during the late 1970s through the 1980s:
- Daniel D. Corkill. Blackboard Systems, AI Expert, 6(9):40-47, September, 1991.
- An overview of the blackboard approach, condensed to fit
publication constraints. This article discusses the characteristics
and potential of blackboard systems. It describes what a blackboard
system is and what it isn't, considerations for using blackboard
systems, and how to get started with a blackboard system.

- A collection of classic (and not so classic) blackboard system and application papers and articles written before 1986. Some were revised for this book. The Introduction and Conclusion chapters provide excellent introductory reading, and Chapters 2-4, 6, 12-14, and 26 provide an introduction to the following major blackboard systems: Hearsay-II, AGE, Hearsay III, BB1, and UMass GBB.

- This book contains descriptions of research on blackboard architectures and their applications during the period 1987-1988. UMass GBB and the precursor to NetGBB are discussed in the following chapters: “Design Alternatives for Parallel and Distributed Blackboard Systems,” by Daniel D. Corkill, and “Performance Aspects of GBB,” by Kevin Q. Gallagher and Daniel D. Corkill.

Engelmore and Anthony Morgan, editors, pages 503-518.)
- The classic retrospective on the first blackboard-system application. The article describes the characteristics of the speech understanding problem as known at the time, the special kinds of problem-solving uncertainty inherent in the problem's domain, the structure of the Hearsay-II system that was developed to cope with that uncertainty, and the relationship between the structure of the Hearsay-II system and the structures of other speech understanding systems of that era.
The following articles and papers describe the UMass GBB system (1984-1989):

In Proceedings of the National Conference on Artificial Intelligence, pages 1008-1014, Philadelphia, Pennsylvania, August 1986. (Also published in Blackboard Systems, Robert S. Engelmore and Anthony Morgan, editors, pages 503-518, Addison-Wesley, 1988).
- This paper describes the original UMass GBB system, the generic blackboard development system that was developed at the University of Massachusetts in Amherst. The paper outlines the reasons why UMass GBB is unique, and it describes GBB's blackboard structure and objects, implementation and instantiation of the blackboard database, and unit creation and retrieval.

Bond and Les Gasser, editors, pages 451-456, Morgan Kaufmann, 1988.)
- This paper discusses the data abstraction techniques used in the
UMass GBB system to overcome the problem of conflicting goals in
achieving flexibility, efficiency, and generality in a blackboard

- This article describes the requirements for problem-solving
architectures that can be embedded within other architectures and that
can coexist with other instances of themselves and of other systems.
It focuses on experience gained in embedding the public-domain version
of OPS5 within the UMass GBB system.

- AI researchers have used the paradigm of collaborating software
systems to tackle large and difficult problems. This invited
presentation compares and contrasts two markedly different
collaborating-software approaches: blackboard systems and multi-agent
systems. Examining collaborating software from both perspectives
provides insights into the nature of collaboration, reveals unresolved
problems in integrating disparate contributions, and underscores
issues in coordinating collaborative activities.
