Staying updated on new publications can sometimes be a big challenge. Particularly considering the growing number of journals and articles from different parts of the world, which is in itself a very positive thing, it is difficult to know exactly who is publishing what, where and when. There are different ways of addressing this problem. For example, I receive several email alerts from major journals that let me know when they have new articles. This is however not a perfect system, because I might be missing on great articles being published elsewhere.
A very interesting solution is the nep-geo mailing list, managed by Andreas Koch, that regularly sends out a list of working papers in economic geography. It has the additional benefit that these are working papers and are therefore accessible free of charge. All you have to do is go to the link above and submit your email address. There is also the nep-ure mailing list, specialised in Urban and Real Estate Economics.
