Hello there! I am looking for some sort of software that, from my limited research, doesn't seem to exist. I work as a consultant and I read articles and books all over the web that contain information to which I'd like to come back once in a while. I'm looking for some software in which I could store the said articles in a way that make it possible to search them with keywords. Being able to write small summaries would be a great bonus and I'd also like to be able to keep references to paper books and articles. I tried using Delicious and as good as it is as an online solution I need something more robust and that I can consult offline. I'll probably be copying and pasting articles to make sure to be able to read them once the links are broken. Anyone know what I could use? I'm of course willing to pay a price since it will help me tremendously in my work. Thanks in advance for your help!
