Hotlists:
But NOTE WELL: in Mosaic and Mosaic-like browsers,
there is usually a "hotlist" feature (in Netscape it's called "bookmarks")
-- if you are looking at a valuable resource on screen and want to come
back, add it to your hotlist and it will be on a pulldown menu for every
subsequent session on the same machine. (You may also delete obsolete
items from your hotlist.)
