The au...... Jun 1 1991     Data caching issues in an information retrieval system Alonso R., Barbara D., Garcia-Molina H. ACM Transactions on Database Systems 15(3): 359-384, 1990.  Type: Article The concept of quasi-copy that this paper discusses abstractly is already in use in non-computerized information retrieval systems. The authors discuss most of the issues involved and present an analytical model that suggests that perf...... Mar 1 1991     The vulnerability of vote assignments Barbara D., Garcia-Molina H. ACM Transactions on Computer Systems 4(3): 187-213, 1986.  Type: Article Voting is a solution to allowing correct executions in a distributed system in the presence of failures. This solution has been studied by the authors in earlier papers (e.g., [1]), while this paper presents their most recent findings....... May 1 1987     How to assign votes in a distributed system Garcia-Molina H., Barbara D. Journal of the ACM 32(4): 841-860, 1985.  Type: Article This paper studies the relationship between two methods of deciding whether a subset of the nodes of a distributed system has access to protected data during a partition. A vote assignment is a mapping of nodes into the nonnegat...... Mar 1 1986
