I am using some time now the Beamer class for my presentations, courses, etc. Recently I found in a book for LateX (dated from 1999) that there is a standard document class called slides for presentations.
Searching in Internet I did not find any information. Is it considered obsolete compared to Beamer class?
Comparing beamer and slides is like comparing apples to oranges - both classes have a different focus.
slides is primarily meant to create slides for overhead projectors. You can see this for example from the default paper size of this class (A4 or letter).
For beamer on the other hand, the default output is meant for video projectors
Warning: The implementation is still very experimental and may change internally very much.– Phelype Oleinik Apr 12 '18 at 13:21slidesis primarily meant to produce real slides, e.g. for overhead projectors – samcarter_is_at_topanswers.xyz Apr 12 '18 at 13:32slidesserves another purpose therefore. – Dimitris Apr 12 '18 at 14:13
