BIll's suggestion is a good one.
When I was younger, I'd accept any 78 rpm record that was offered to me. I wound up acquiring a lot of stuff from the late 1930's - 1940's, which generally should not be played on acoustic talking machines ( softer record material, wear quickly on an acoustic machine ). Plus that music is readily available as CD compilations or digital down-loads.
I like to collect pre-1935 records, with emphasis on 1920's jazz, and earlier recordings.
I have favorite artists - Billy Murray, Collins & Harlan, John McCormack, Vaudeville stars, etc.
Favorite genres = Comedy, Classical music, Minstrel tunes, "Car" or "Train" songs, Military Bands & Marches
Favorite tunes - "He'd have to get out and get under", "The little Ford rambled right along", "Aunt Dinah's Golden Wedding", etc.
I prefer to buy records in person - that way I can see condition before buying. If it's a "lot" of records, and the price is right, I might just grab the whole box, and sort later.
E-bay can be risky, as much for the seller being able to pack the records so they survive the trip as anything else. I've had 50% of my e-bay records arrive in pieces.
Talking machine meets are great places to find records- many sellers have their records sorted by era / genre / artist, etc. and you can find reasonable deals. There's one twice a year in Wayne, NJ, and also at Union, IL.
There are also a few reputable dealers who hold record auctions periodically, who have catalog listings, and who know how to pack for safe shipping.
Thrift stores and estate sales are also great places to look.
Unless it's a "special" record ("rare" or fits-in with my criteria), I try to spend $1 or less for a 10-inch disc.
