This index is intended to be comprehensive in order to enable one to find any music related subject quickly. It is also intended to provide quick access to philatelic subjects such as postmarks, proofs and essays.
Not everything is indexed. For example, company names under “Advertising” are not indexed because they are in the indexed album in alphabetical order. Likewise, countries are not indexed because they are arranged in alphabetical order under each subject. Types of musical instruments are listed in alphabetical order, except for exotic native musical instruments. These are in country of depiction order.
Stamp issues are not indexed since they can be found on the Accession sheets. To find them in the collection, simply look up the subject illustrated. Everything is categorized according to design or subject.
