Good reading:

A. T. Cohen, "Data Abstraction, Data Encapsulation and Object-Oriented
Programming," in SIGPLAN Notices 19:1 (Jan 1984), pp. 31-35. 

The author attempts "to draw a clear-cut and useful distinction among
them [the three terms of the title] and to show that they describe
complementary aspects of the general idea of information-hiding."
I found the article to be well-written and quite helpful in untangling
the terms and the ideas they represent.
