The problem statement is asking for a SQL query that retrieves detailed information about books from a library management system. The system has tables for publishers, library branches, books, book authors, book copies, and book lending.

Here is a step-by-step guide on how to write the SQL query:

1. Identify the tables and the fields you need to include in your query. From the problem statement, you need the following fields: Book_id, Title, Publisher_Name, Pub_Year, Author_Name, No_of_Copies, Branch_Name, Branch_Address. These fields are likely spread across multiple tables.

2. Determine how the tables are related. Usually, tables in a database are related through primary and foreign keys. For example, the books table might have a publisher_id field that matches the id field in the publishers table.

3. Write the SELECT statement to specify the fields you want to retrieve. For example:
```sql
SELECT books.id AS Book_id, books.title AS Title, publishers.name AS Publisher_Name, books.pub_year AS Pub_Year, authors.name AS Author_Name, copies.number AS No_of_Copies, branches.name AS Branch_Name, branches.address AS Branch_Address
```

4. Use JOIN statements to combine the tables based on their relationships. For example:
```sql
FROM books
JOIN publishers ON books.publisher_id = publishers.id
JOIN authors ON books.author_id = authors.id
JOIN copies ON books.id = copies.book_id
JOIN branches ON copies.branch_id = branches.id
```

5. If there are any specific conditions you need to meet, use a WHERE clause. In this case, there doesn't seem to be any conditions, so you don't need a WHERE clause.

6. Finally, you might want to order your results in a specific way using an ORDER BY clause. In this case, the problem statement doesn't specify an order, so you don't need an ORDER BY clause.

Here is the complete SQL query:
```sql
SELECT books.id AS Book_id, books.title AS Title, publishers.name AS Publisher_Name, books.pub_year AS Pub_Year, authors.name AS Author_Name, copies.number AS No_of_Copies, branches.name AS Branch_Name, branches.address AS Branch_Address
FROM books
JOIN publishers ON books.publisher_id = publishers.id
JOIN authors ON books.author_id = authors.id
JOIN copies ON books.id = copies.book_id
JOIN branches ON copies.branch_id = branches.id
```

Please note that the exact field names and table names might be different in your actual database. You would need to adjust the query accordingly.
