How to tag journals/books?

Q: How should we bookmark books, and journals on Delicious? Generally, these full texts are not available online or are password protected.

A: We can bookmark publishers’ or Amazon.com’s book pages for books. We can bookmark journal articles’ abstract pages for password protected journal articles.
