I found two good PDF's on the interweb of Bohr's seminal papers (Published in Phil. Mag., 1913) on atomic structure. I couldnt find part 3 unfortunately.

On the Constitution of Atoms and Molecules

Part II. – Systems containing only a Single Nucleus

Also Rutherfords papers on the gold foil experiment and large angle scattering of alpha & beta particles that led to Bohr's enunciation of the nuclear/quantized model of the atom.

The Scattering of Αlpha and Βeta Particles by Matter and the Structure of the Atom (Phil Mag 1911)

The Structure of the Atom (Phil Mag 1914)

Donald Sadoway, MIT, does a really nice job of covering the Bohr model in the following lectures (3.091 Intro to Solid State Chemistry). Requires Real Player (Or Real Alternative if you please).

Lecture 3. Rutherford model of the atom, Bohr model of hydrogen.

Lecture 4. Atomic spectra of hydrogen, matter/energy interactions involving atomic hydrogen.

Lecture 5. The Shell Model (Bohr- Sommerfeld Model) and multi-electron atoms. Quantum numbers: n, l, m, s.
