Older datasets are available on a daily basis and can be found

Data is available from 2007-05-30 onwards.
The file constitutes an anonymous dump of who posted
what and when the posting took place. There is no
data in this file which is not already available publicly through the
web site, so there are no privacy implications for making it
available. The advantage is that it’s available in one file rather
than having to spider the entire site to get at the information
(please don’t do that!).
The file is a simple unix (“\n” line endings) text file with pipe (“|”)
delimiters. The columns are:
- The CiteULike article id which was posted
- An obfuscated representation of the username (a salted MD5 hash of
the true username). Again, it is possible to piece back together what
the true username is by scraping the site, but I’d rather you didn’t
do that. The reason I’ve gone to the trouble of obfuscation is
primarily a slightly paranoid anti-spam measure
- The date and time the article was posted to the site
- The tag the user used to post it
NB Note that if a user posts an article with n
tags, then this will result in n rows in the file
Article linkout data
Mapping CiteULike article_ids to resources on the web can be done
with the linkout table. The current snapshot is available at http://static.citeulike.org/data/linkouts.bz2
