How to Use the Repertory, by Glen Irving Bidwell, was published in 1915. As a student of Kents Bidwell had the opportunity to learn the proper application of the repertory. This work is his effort to disseminate this knowledge as widely as possible. There are two sections to this book. The first covers the use of Kents Repertory; the second part is a materia medica of 40 remedies. Bidwell utilized the second edition of Kents Repertory as he felt this was "the most simple and satisfying to use". He felt that the repertory was never made or intended to take the place of the materia medica. Bidwell stressed the fact that "it must never replace our constant study and use of the pathogenesis of our remedies, it should be used as an index to lighten the task of memory in storing the vast symptomatology of our remedies." After the repertory work leads the homeopath to the most likely remedy, the selection of the remedy needs to be confirmed by reading its pathogenesis in the materia medica.
