**The Best Sources**

**Becker, Becker, Schwarz**, *String Theory and M-theory* has a wide scope (from classical bosonic strings to BFSS Matrix theory (and a bit of Matrix string theory), and a bit about F-theory) and discusses the topics very intuitively. I've not read GSW, but I've heard that BBS is a modification to that (old) book. Can be downloaded from http://www.gen.lib.rus.ec (not a pirate).

**McMahon** *String Theory Demystified* has a rather wide scope but relatively less depth. Could once be downloaded from a pirate site, which no longer exists.

**Mohaupt** *Introduction to String Theory* has a limited scope and depth, but covers the gravitational implications of string theory rather deeply. Can be downloaded here: http://arxiv.org/abs/hep-th/0207249v1.pdf

**Kaku** *Strings, Conformal fields, and M-theory* is an extremely rigorous, rather unintuitive, rather wide and deep, source for learning string theory.

**Two More Sources**

**For String Field Theory**

I am planning to read this lecture notes with a supposedly better (PDF only, no abstract page) version here.

Also, these lectures by Shiraz Minwala were suggested by Larry Harson in the comments.
