Phonograph related Research Topics

Researchers provide great value to our hobby. They spend a lot of time collecting and organizing phonograph related information and they depend on input from other collectors. Unfortunately these research topics and questionnaires get buried over time in the forum and become hard to find, so here are direct links for your convenience. Please consider participating if you have relevant information to share.
