This enables them to convey a large amount of information in a relatively short space, but readers not completely fluent in those languages are likely to be left somewhat bewildered, even discouraged, by strings of vowels and consonants occurring either singly or in unfamiliar combinations in the midst of what would otherwise be a fairly comprehensible text. For them, this little dictionary, the first one of its kind, I think, may come in handy.

Thus, its history is comparable to that of a person. Information retrieval had its schoolboy phase of research in the 1950s and early 1960s; it then struggled for adoption in the 1970s but has, in the 1980s and 1990s, reached acceptance as free-text search systems are used routinely. The tension between statistical and intellectual content analysis seemed to be moving towards purelyg statistical methods; now, on the Web, manual linking is coming back.
