Does anyone know how I can easily download all of the pubmed article abstracts? I am working on a text mining project.
The closest one I can find can download one abstract at a time given an pmid, but that would be too slow for my purpose since I'd have to download them one at a time.

Searching for "0000/01/01"[PDAT] : "3000/12/31"[PDAT] should get you every article from the beginning of time.
Maybe the "sent to" function shown right-above the search results will let you download everything.
Alternatively, you can write a script and use the Entrez programming utility from the NCBI.
You can perform a search query using ESearch, which will return all PMID's. Then you can use EFetch to return all data. It is explained in this book/manual: http://www.ncbi.nlm.nih.gov/books/NBK25501/
Chapter 3 contains some example scripts which should get you started: http://www.ncbi.nlm.nih.gov/books/NBK25498/#chapter3
You will get xml files containing the abstract and all other data.
25 million XML files...

I am aware this has gone a bit stale, but they have a process for your exact same use case - large scale mining projects.
You can get the data via a free licensing agreement - more information here.

You can get ALL the data from NLM directly via FTP.

Download and work away without worrying about e-utils.
I would use RESTful API provided by Europe PMC. They allow to download 25 articles per query in json or xml format. Example queries for articles about malaria would look like:
You can use different format of search query, it depends what you really want to retrieve.
