Solution 2

"Publicationname AND Authorname": that is a Boolean value, surely not what you want to get.
Guess that you want to see both values, use a comma in between, and in your WHERE clause test two conditions which are linked with AND.

SQL

Select a, b 
From aTable
Where a='valueOfA' AND b='valueOfB'
