The best advice so far!
In the early days, books that deal with the history and philosophy of aikido are probably best. Reading Aikido in Daily Life by Koichi Tohei started me on my aikido journey, but I think " The Spirit of Aikido" by K Ueshiba was a great little book for giving a really good overall picture.
