There are a number of textbooks available, if you were interested in serious self-study. I don’t know of specific names off-hand. A dictionary would be important as well to have as a reference. You could start with a beginning textbook to get basic grammar and vocabulary, then eventually move up to advanced grammar and then actual ancient texts. These would probably be transcribed to a familiar font with hints to help through things like common abbreviations. There are some conventions to learn before being able to read actual artifacts - when you’re paying to have stone carved by the letter, abbreviations are going to be frequent.
