For sure a problem in many subject areas.
I've been pleased (on Macintosh) with the offline bookmark manager URL Manager Pro
At your command it will bookmark sites you visit; you organize the sites into folders; it stores the data on your hard drive, independent of the browser; each link has a memo field where you can add keywords, personal impressions, or text clips from the site; later search for any word or URL. For me, a big help.
