I use the online tool citeulike to manage my bibliography. The main tool to organize the library is tags (functionally equivalent to tags here on this site). One problem I seem to be having is I do a very poor job of initially choosing tags, so I need to continually re-tag my library to keep it organized.
Is there any advice on choosing an intitial set of tags? Or will it be necessary for me to continually maintain my library to keep it organized/updated as much as I would like?
I don't use citeulike myself, but I think it's important to make a difference between tags and keywords. Indeed, keywords are usually already included in the paper or at least in the abstract, so you don't need to retag them with duplicate information. Instead, it's better to use tags to give some personal context, such as why did you read this paper in the first place, or which general idea can you connect it to, or for which of your papers you used it, etc. In this case, there is no "wrong" or "right" tag, just some facts.
