There is no better sports card guide than Beckett.  This is the most comprehensive guide on the market. With baseball card prices going back to the good old tobacco cards of the early 1900’s to the most modern cards on the market. These books have come a long way and are much bigger than they were back in the 1990’s when they were wafer thin. Most certainly the most bang for your buck if you want the latest on baseball cards. Nice articles too that will get your juices pumping to go out and purchase more cards! Happy collecting!
