For Ceremonial Magic I would say that the major source texts are your classical grimoires and of course Agrippa so:
Three books of occult philosophy by Agrippa
The keys of solomon: Joseph Peterson version.
The magical papyri: I believe Stephen Skinner has brought out an edition of this, I would go for that one.
The Kybalion by Three Initiates.
For modern ceremonial magic:
Transcendental Magic by Eliphas Levi.
The Golden Dawn by Israel Regardie.
Liber ABA by Aleister Crowley.
If you want a watered down beginner version: Modern Magic by Donald Michael Kraig.
A more detailed beginners book is "High Magick" by Frater UD which also has reading recommendations.
Of course there are many different traditions, but here are some titles I loved:
Traditional Witchcraft:A Cornish book of ways by Gemma Gary
Devil's Dozen by Gemma Gary.
The Black Toad by Gemma Gary.
The Dragon Book of Essex and Azoetia by Andrew Chumbley.
Book of Fallen Angels and Children of Cain by Michae Howard.
Treading the Mill by Nigel Pearson.
A History of the Pendle Witches and Their Magic by Joyce Froome.
A deed without a name by Lee Morgan.
