I am new to collecting vinyl. And please excuse my naivety and my, probably very elementary, question. But when I am record shopping how do I: 1) Tell the difference between a limited edition pressing 2) Tell the difference between a first run pressing if they don't say anything on the package or sleeve? The reason I ask is because I recently was shopping and bough a couple of albums I really wanted on vinyl. So I didn't care if they were limited/first run or not. But, to my delight when I got home I found that they were. I am aware of the Discogs.com database. But I am wondering if there is a quicker way to find out just by looking at the record itself while I am searching the bins? Any help would be appreciated. Thank you everyone!! - John
