I just tried to import the philosophy of physics papers from my CiteULike library into PhilPapers. There doesn’t seem to be a way to import citations from a BibTeX file; we can import them only in plain text format. So I used CiteULike’s citation export function to get a text bibliography of the papers, did some painstaking editing to make sure there was only one paper per line, and input the list into the box provided under “Batch Import” for each category in PhilPapers. It recognised only about a quarter of the papers on there. Next, I tried importing all the papers tagged “time” in my library, and none were recognised. (Yes, I will put this feedback on the PhilPapers forum have submitted my feedback on this issue.) So at this point of time I’d still stick with CiteULike, especially when it also has social tagging functions that PhilPapers doesn’t. I’ve found many an interesting paper tag-surfing on CiteULike. I can also see who has libraries similar to mine, see what is in their libraries, and choose to “watch” their libraries for any new items they add.
I have to say I’m not as excited about PhilPapers as many others seem to be, because I already keep up with new papers via journal RSS feeds and Online Papers in Philosophy, and I was already very satisfied with CiteULike’s provisions for keeping track of papers I read. Also, it’s nice to have all the papers I read, whether in philosophy or the natural sciences or social sciences or computer vision, in the same place, and I can do that on CiteULike but not on PhilPapers.
