What is the difference between guide words and entry words?

Answer 1

Look in any dictionary (book, not online!)

At the top of each page is a guide word - usually the first or last entry on the page.

In the dictionary are words printed in alphabetical order. Each of these entries is an entry word.

You could have found this out by googling or looking up in a dictionary :

Entry word - Noun, entry word - the form of a word that heads a lexical entry and is alphabetized in a dictionary. citation form, main entry word

Guide word - word printed at the top of a page in a dictionary, encyclopedia, etc., usually the first or last entry on the page

Answer 2

Guide words are the first and last words on a dictionary page, helping users locate a word alphabetically. Entry words, on the other hand, are the main words listed in a dictionary with their definitions and other relevant information. Entry words are what users look up to find the definition of a word.
