Simply remove all rows from the biblio table, define a query with the
columns you actually want to user and enter your own data into the query.
Don't try to build a fully functional relational database from scratch
unless you have some basic knowledge about database design which is well
paid development work.

Before you delete all rows from the existing biblio table, go to the
queries section, create a new query in SQL view and paste the following:

SELECT "Identifier","Author",
"Custom1" AS "Language",
FROM "biblio"
ORDER BY "Author"

Save and close the query and double-click its icon.
It selects only those columns of the shipped table which contain some
data in arbitrary order of columns (I rearranged them in alphabitical
order) while sorting the rows by autor name. The "Custom1" column is
renamed to "Language" because this is the actual content of that column.

You could use this subset of a table just like you would use the
original table. Everything you enter in the query will be entered into
the corresponding field of the table.

DELETE FROM "biblio"
deletes all records from the biblio table. You can also click the grey
top left corner of the opened table which selects all records and then
delete all selected rows by button or context menu.
