用Python写一个基于链式存储的图书信息管理系统，（1）首先将该文件中的图书信息读入到一个链表中 （2）至少实现以下6个功能：查找、插入、删除、修改、排序、显示所有图书信息等，

在Python中，我们可以使用类（class）和链式数据结构（如节点ListNode）来构建一个简单的图书信息管理系统。下面是一个基本的设计：

# 定义图书节点类
class BookNode:
    def __init__(self, title, author, id):
        self.title = title
        self.author = author
        self.id = id
        self.next = None

# 图书管理链表类
class BookList:
    def __init__(self):
        self.head = None

    # 插入函数
    def insert(self, title, author, id):
        new_node = BookNode(title, author, id)
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node

    # 查找函数
    def search(self, id):
        current = self.head
        while current and current.id != id:
            current = current.next
        return current is not None

    # 删除函数
    def delete(self, id):
        if not self.head:
            return
        if self.head.id == id:
            self.head = self.head.next
            return
        prev = None
        current = self.head
        while current and current.id != id:
            prev = current
            current = current.next
        if current is not None:
            prev.next = current.next

    # 修改函数
    def update(self, old_id, new_title, new_author):
        current = self.head
        while current:
            if current.id == old_id:
                current.title = new_title
                current.author = new_author
                break
            current = current.next

    # 显示所有图书信息
    def display(self):
        items = []
        current = self.head
        while current:
            items.append((current.id, current.title, current.author))
            current = current.next
        for id, title, author in items:
            print(f"ID: {id}, Title: {title}, Author: {author}")

# 示例用法
book_list = BookList()
# ... (从文件或其他源读取图书信息并插入链表)

# 调用各种操作
book_list.insert("书名", "作者", 1)  # 插入图书
if book_list.search(1):  # 查找特定图书
    print("找到了")
else:
    print("未找到")
book_list.delete(1)  # 删除图书
book_list.update(1, "新书名", "新作者")  # 修改图书
book_list.display()  # 显示所有图书信息

这个例子是一个基础版本，实际应用中可能会需要处理更复杂的情况，例如错误处理、文件输入/输出以及链表遍历优化。
