I think what you need to do is place a TTable component on your form, and set the table property to the name of your paradox table,

then, assuming the column name is 'Name'

.....

table1.Open;
table1.first;
if table1.locate('Name', 'book', [loPartialKey]) then
  showmessage('Found')
else
  ShowMessage('Not Found');

.....

the loPartialKey bit should mean you find any string containing 'book'.

Sorry johnstoned,

but when you use loPartialKey you'll find <book> only if it's in the begining of the searched words. In Paradox there isnt't a statment for that kind of searching. In InterBase there is a CONTAINING staitment that makes all that you want, but unfortunatly Paradox don't supported it.
If you use Paradox you must create a function that collate every substring of field when you looping trought the table records. If you want some source I'll write some for you.

Regards
Ivan

Why not use SQL?

like so:

Select Field1, Field2 from database.db
  where Field1 like "%book%"
order by Field1
