For convenience, I often want to give a link to a research article in addition to the citation. I am mostly look for the following two properties:
- the link should be valid as long as possible
- the link should provide as many sources as possible to download the article, ideally free of charge whenever available.
I use Google scholar, e.g.: Godbole, Shantanu, and Sunita Sarawagi. "Discriminative methods for multi-labeled classification." Advances in Knowledge Discovery and Data Mining. Springer Berlin Heidelberg, 2004. 22-30.
I link to the "all versions" page:
Are there other any good/better alternatives?
