This handy pocket-size Bilingual Spanish and English Hymnbook Index allow one to locate hymn numbers of hymns in both the English and the Spanish LDS hymnals. It contains two separate indexes. Both of them indicate the hymn numbers for all the hymns side by side: English and Spanish. Spanish speakers can look up hymn numbers in the Español-Inglés Indice Himnal. English speakers can lookup hymn numbers in the English-Spanish Hymnbook Index. The two listings also indicate when hymns are not translated and published in the hymnals in the other language. The complete index is available in two sizes. The pocket-size index fits the 3.5″ x 5″ pocket-size hymnals. The standard-size index fits the regular 6″ x 9.25″ green hymnbooks. Users frequently glue them to the inside back cover of their hymnbooks.
