The First amendment secures several different, but related, rights:
Congress shall make no law...
1) respecting an establishment of religion, or prohibiting the free exercise thereof;
2) or abridging the freedom of speech,
3) or of the press;
4) or the right of the people peaceably to assemble,
5) and to petition the Government for a redress of grievances.
What I underlined, above, is the right to read and publish.
