Go get a copy of the old Texas Instruments standard, "The TTL Data
Book." If you get into the field, you will use it the rest of your
life. In the meantime, you can sometimes find datasheets via a google
search, downloadable in .pdf format. The datasheets will make a good
accompaniment to reading of basic digital circuits. The prefaces in the
"Data Book" are good to read, as they give some description of the
operation of the IC's listed inside. The first and most important gate
to learn: the NAND gate. Packs a lot of concept in one neat package.
