("A" indicates that only author entries were tallied; "T" indicates that only title entries were tallied. Where detected, duplicate entries have been omitted. For entries not specific to Latin America (personal names; titles like "Boletin" or "Revista"), only known Latin American materials have been tallied. Some sources, particularly MIP and BGM, suffer from occasional coding errors for initial articles in titles and the consequent misfiling of entries. The tallies do not adjust for such anomalies.)

B. Main entry "Venezuela": 177 author or title entries.
