Studies in Coordinate Indexing.

Here Taube developed Coordinate Indexing, and important innovation in the field of Library Science.

• Coordinate indexing (domestic deep indexing systems, keyword indexing)

He was important to the Library Science field because he invented Coordinate Indexing, which uses "uniterms" in the context of cataloging.

Taube defines Coordinate Indexing as, "the analysis of any field of information into a set of terms and the combination of these terms in any order to achieve any desired degree of detail in either indexing or selection."
