Without knowing what you've read, it's difficult to give suggestions that will, with any certainty, "hit the spot." That being said--with nods to the gentlefolk who have written thoughtful responses above--here are some more suggestions:
I think any student of magic--but particularly people delighted by history--would be well served by the Dover reprints. They are cheap--and truly wonderful--stuff.
Albert Hopkins "Magic, Stage Illusions, Special Effects and Trick Photography" is still out there for around $14.00. 556 pages of great history, illustrations, and an interesting multi-lingual bibliography. Dover 0-486-26561-7 $13.95
Milbourne Christopher "Magic: A Picture History" is an abridged version of the larger Christopher work listed above. At $15.00, it is a delightful, but less substantive overview. 0486263738
Edwin Sachs "Sleight of Hand" This is not truly a history. Instead, it is a historical document which ANYBODY interested in either history or sleight of hand should read. $10.95 048623911X
Gibbon & Young "Houdini on Magic" (Some of the cognoscenti are cringing.) But it's really worth a look. It's an edited selection detailing a rich variety of historical information on escapes, spiritualism and the history of magic. It has a particular slant--but what book doesn't? $7.95 0486203840
Other basic stuff:
The Art of Magic by Waldman/Layden/ J.I. Swiss is a wonderful paper version of the PBS series.
Jim Steinmeyer's forthcoming book "Hiding the Elephant How Magicians Invented the Impossible and Learned to Disappear" (0-7867-1226-0 $26.00) Is one of the best "overviews" of magical history written in the last 50 years, and it will be available in a month or so. Check your local book shop.
If you haven't read Ricky Jay, find him and read him. It's not "just magic." It's Just Magic.
If you have travelled through these books, and want more, look for names like Jim Steinmeyer, Mike Caveney, John Booth, Edwin Dawes, anything put out by Miracle Factory; many of the books published by our host, Mr. Kaufman; the reprints Joe Stevens is still offering; the books published by Mr. Minch at Hermetic Press; old issues of Genii, the Linking Ring, etc. Many-- too many--to name them all or do justice to them.
If you like reading online there are possibilities that boggle the mind. Write "ebook" in a reply, and someone will find you and point the way. :-)
Or comb the pages right here. You've discovered an amazing resource just by logging on. Pose a question here about magic history, and some one WILL know the answer.
But I digress...and in digression traverse the gap to silence.
Here's hoping you find something good to read....
