The problem statement is asking for a SQL query to retrieve details about books from a library management system. The tables in the system include 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.

2. Identify the relationships between the tables. You will need to join the tables based on these relationships. For example, the books table might have a publisher_id field that corresponds to 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. Write the FROM statement to specify the main table you are selecting from. For example:

```sql
FROM books
```

5. Write the JOIN statements to join the other tables. For example:

```sql
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
```

6. If necessary, write the WHERE statement to filter the results. In this case, no filter is specified in the problem statement, so you don't need a WHERE statement.

7. Put it all together to get the final 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
```

This query will retrieve the required details about the books. Please note that the exact field names and table names may vary depending on the actual structure of your database.
