The following overviews, resources, scientific papers, etc., I recently compiled for our resident "globular cluster fanatic" Dana, as being an "extension" to his interests in clusters and stellar evolution. But I may as well list them here, so they can be accessed by all and sundry!
These are amongst the best papers, from my last few hundred downloads.......
the impossibly large numbers of papers constantly added to arxiv (the preprints server) are probably due to the unprecedentedly large number of bright young astronomy PhDs and post-docs who are just entering the field. I have been intensively following research astronomy for some 23 years, from a total period of 40 years interested in astronomy), and I can say that there have never before been anywhere near so many young workers entering the field at one time.
_______________
1) Attached is a really useful and really recent overview about the bulge of our close neighbour and old friend, M31.
163610
The actual published reference is: 2013, PASA, 30, 27
(Proceedings of the Astronomical Soc. of Australia)
Neither bulge nor halo of M31 are like that of the MW, and its disk is also entirely different (M31 disk is gas poor, with low intensity of star formation; )
______________________
(2) Attached is a very concise, and easy-to-read, review paper about the bulge component of our own Galaxy.
163609
This is: Minniti & Zoccali (2008) in IAU Symposium 245 "Forrmation and Evolution of Galaxy Bulges"
Unfortunately, the information about the stellar populations within the bulge is already (!!) out of date. In particular, Ken Freeman and Joss Bland-Hawthorn have whipped up a storm of interest in accurately characterizing and understanding the nearest bulge.

(3) This ARAA 2012 review , by Ivezic & Beers and Juric, about the disk and bulge of our own Galaxy, is relatively accessible, and it at least attempts to explain the concepts.

(4) Here is a very detailed overview of the stellar disk component of our own MW galaxy.
It is not quite as overspecialized as Freeman's recent intricate efforts based on radial velocity and spectral surveys of our Galaxy, therefore it is more suitable for the "lesser brethren", but I still find parts of it to be difficult reading!

Certain new species (?) in the zoo of massive stellar aggregations that are not quite clusters and not quite galaxies (or perhaps a bit of both) : :
http://adsabs.harvard.edu/abs/2012A%26A...547A..65B
(http://adsabs.harvard.edu/abs/2012A%26A...547A..65B)As Dana said, when we look outside of the fairly tame (= with a low & steady Star Formation Rate) environment of the local regions of our own Galaxy, star cluster studies get very complicated....because there are a great variety of star cluster types that we are not really familiar with.

And yet more complexity in the cluster zoo...... the Nuclei of elliptical galaxies.....
These objects perhaps DO NOT seem to follow the size and luminosity distributions, and the scale relations, of normal Compact & Massive Star Clusters like globulars:
http://adsabs.harvard.edu/abs/2012ApJS..203....5T
But see also:
http://arxiv.org/abs/1205.5338
This paper provides comprehensive data on Nuclear Star Clusters in galaxies, star clusters which for the most part seem to resemble more massive and more luminous versions of standard globular clusters, BUT with younger populations of constituent stars.

The (relatively) young Globular Clusters found in the galaxy NGC 4636:
http://adsabs.harvard.edu/abs/2012ApJ...759..116P
This is a relatively new discovery (unlike in the merger remnant NGC 1316, where the youngish GC population has long been known). This paper also has a good summary of previous work done on the GCs of giant elliptical galaxies.
Incidentally, Kormendy and Fisher and Cornell and Bender, in their fantastic catalogue of the morphology and photometry of Virgo Cluster elliptical galaxies( 2009. ApJS, 182, 216), suggest that NGC 4636 is actually a face-on S0 galaxy (a disk+bulge system).

The star clusters in the intensely star-forming spiral galaxy M83::
Here are four Studies of its population of massive star clusters, deriving their ages and masses (etc.) , and done with the Hubble Space Telescope. It would seem that this galaxy does have youngish (= less than a few times 100 million years old) star clusters of 100,000 solar masses each, and also a few star clusters which are even more massive than this, which is as you would expect if there were larger numbers of giant nebular complexes than in our own galaxy. In general, the disk S.F.R. in M83 is thought to be well elevated over the value that we find in our own Galaxy, but it is not a well studied parameter. There are some tentative hints in this work that, perhaps, the most massive new star clusters (one million solar masses, and up) may not form in the disks of spirals (for the most part), but only form in galaxy collisions and in dwarf irregular galaxies.
http://arxiv.org/abs/1402.3595
This team promises to publish a study of the entire M83 disk population of star clusters that are over 5000 solar masses.
http://www.aanda.org/articles/aa/abs/2011/05/aa16206-10/aa16206-10.html
This paper also studies the cluster system of NGC 1313, a remarkable nearby relatively high-surface-brightness Sd galaxy which is undergoing a global burst of star formation. One of the most interesting galaxies in the sky for visual observation!

http://iopscience.iop.org/0004-637X/719/1/966
The mass distribution of the youngish clusters along one of the two main spiral arms of M83 is well studied in this ApJ paper.
